How do these forces affect the car's
movement?

The truth that Voyager maintains to hurry out of the sun system, despite the fact that its rockets haven't any fuel, is an instance of Newton's first regulation(law) of movement.

Newton's first regulation states that each item will continue to be at relaxation or in uniform movement in a immediately line except pressured to extrude its kingdom via way of means of the movement of an outside force. This tendency to withstand modifications in a kingdom of movement is inertia. The 3 legal guidelines of movement have been first said via way of means of Isaac Newton in his Philosophie nutralize Principia Mathematica (Mathematical Principles of Natural Philosophy), firstly posted in 1687.

Newton used them to research and provide an explanation for the movement of many bodily gadgets and systems, which laid the muse for classical mechanics.

The period of a satellite orbiting mercury 265,000 m above its surface is 100 minutes if the radius of the planet mercury is 2.43*10^6m and its mass is 3.2*10^23 kg.

v = √ G M / r

r = R + d

v = Orbital velocity

G = Gravitational constant

M = Mass of planet

r = Radius of the orbit

R = Radius of planet ( mercury )

d = Distance from surface to satellite

m = 3.2 * [tex]10^{23}[/tex] kg

R = 2.43 * [tex]10^{6}[/tex] m

d = 265000 m

G = 6.67 * [tex]10^{-11}[/tex] N m² / kg²

r = R + d

r = 2.43 * [tex]10^{6}[/tex] + 265000

r = 2.695 * [tex]10^{6}[/tex] m

v = √ ( 6.67 * [tex]10^{-11}[/tex] * 3.2 * [tex]10^{23}[/tex] ) / 2.695 * [tex]10^{6}[/tex]

v = √ 7.92 * [tex]10^{6}[/tex]

v = 2.81 * 10³ m / s

v = 2.81 km / s

v = 2 π r / T

T = Time period

T = 2 * 3.14 * 2.695 * [tex]10^{6}[/tex] / 2.81 * 10³

T = 6.02 * 10³ s

The distance between the points A and B is 6000 miles.

Let us assume that the distance between the points a and b is D.

Now, we know, airplane takes 4 hours and 48 minutes to move from a to b and back with no wind

Let us say the speed of the airplane is V.

So, we know,

Average Speed = total distance/total time

The distance between a to b and back is 2D.

So, we can write,

V = 2D/4.8

2D = V(4.8)

With wind of speed V'=100mph, it take 5 hours for the airplane to go from a to b ane back.

The average velocity of airplane in wind is,

V + V' = 2D/5

Putting value of 2D,

V + V' = V(4.8)/5

5(V + 100) = 4.8V

5V + 500 = 4.8V

0.2V = -500

V = -2500mph

The negative sign only means that we have taken the opposite direction, so that is not a problem and we can ignore it,

So,

We know,

2D =V(4.8)

D = 2500(4.8)/2

D = 6000 miles.

So, the distance between the two points is 6000 miles.

The velocity of the swimmer relative to the shore is 2 m/s south by vector addition

What is vector addition ?

Vector addition means putting two or more vectors together. In the addition of vectors, we are adding two or more vectors using the addition operation in order to obtain a new vector that is equal to the sum of the vectors. Vector addition finds its application in physical quantities where vectors are used to represent velocity, displacement, and acceleration.

We can solve this problem by using vector addition.

In fact, we can take north as positive direction, and we can write the following:

vc = - 4m/s is the velocity of the current (which is negative, since it is south)

v s= +2m/s is the velocity of the swimmer (which is positive, since it is north)

Therefore, the velocity of the swimmer relative to the shore is

v = vs + vc = 2+(-4) = - 2m/s

And the negative sign means the direction is south, so the answer is

v = 2 m/s south

The velocity of the swimmer relative to the shore is 2 m/s south by vector addition

A verb is one of the parts of speech in English language and it can be defined as a type of word which is used to describe an action, occurrence, experience, or a state of existence such as, smashed, living, contacted, clean, drive, etc.

Speed can be defined as the distance covered by a physical object per unit of time. This ultimately implies that, the higher the speed of a car that is involved in a road crash or accident, the higher would be the level of impact and damage that would be caused.

In this context, we can reasonably infer and logically deduce that changing the verb from contacted to smashed, ultimately implies that the road crash or accident was ghastly and fatal and such would cause broken glasses in the cars that were involved.

The constant velocity of the body on the frictionless surface is represented by the frictionless surface acceleration. No net force on the moving object can stop it from going when the surface is frictionless. As a result, the body keeps moving at the same speed. The skater has no net acceleration if no forces are operating on him and he is on a frictionless surface. The acceleration must be zero since the skier must have mass. If there is no acceleration when an item is moving, its velocity stays constant.

The center of mass exists a position defined relative to an object or system of objects.

The unique location where the weighted relative position of the scattered mass adds to zero is known as the center of mass in physics. Here is where a force can be applied to produce a linear acceleration without also producing an angular acceleration.

A position established in relation to an object or set of objects is the center of mass. It represents the system's average location as weighted by each component's mass. The center of mass for straightforward stiff objects with homogeneous density is found at the centroid.

Given:

Mass of car, m = 1150 kg

Distance, d = 2.35 m

The new position of center of mass will be:

[tex]$=\frac{1150 \times 2.35+160 \times 2.7+240 \times 3.75}{240+260+1150} \\[/tex]

The Work - Energy theorem states that the work done by the sum of all forces acting on a particle equals the change in the kinetic energy of the particle.

The Work-Energy theorem can be applied in circumstances when a rigid body must move while being subjected to several forces. A rigid body can only have kinetic energy because of its rigid structure, which prevents it from storing potential energy in its lattice.

Resultant force of the given forces: approximately [tex]11.2\; {\rm N}[/tex] at approximately [tex]53^{\circ}[/tex] west of south.

Explanation:

The resultant force of these forces will be:

Refer to the diagram attached. The resultant [tex]5\; {\rm N}[/tex] force to the south and the [tex]10\; {\rm N}[/tex] force to the west are perpendicular to each other, forming the two legs of a right triangle. The hypotenuse of this right triangle will be the net effect of these two forces.

[tex]\begin{aligned}(\text{length of hypotenuse}) &= \sqrt{10^{2} + 5^{2}} \approx 11.2\end{aligned}[/tex].

Hence, the magnitude of this net effect will be approximately [tex]11.2\; {\rm N}[/tex].

Let [tex]\theta[/tex] denote the angle between this resultant force and west. In this right triangle:

[tex]\begin{aligned} \tan(\theta) &= \frac{(\text{opposite})}{(\text{adjacent})} \\ &= \frac{5\; {\rm N}}{10\; {\rm N}} \\ &= \frac{1}{2}\end{aligned}[/tex].

[tex]\begin{aligned} \theta &= \arctan\left(\frac{1}{2}\right) \approx 27^{\circ}\end{aligned}[/tex].

Hence, the angle between this resultant force and south will be approximately [tex](90^{\circ} - 27^{\circ}) = 63^{\circ}[/tex]. This resultant force will be at approximately [tex]63^{\circ}[/tex] west of south.
