The given is:Mass – 2000 kg

The given is:Mass – 2000 kgInstantaneous speed – 10 meter per second

Step: 1K.E= 1/2mv^2

Where, K.E – Kinetic energy in joules:

m – Mass in kg

  v – Velocity or speed in meter per second

From the give,

m = 2000 kg

v = 10 m/s

Equation (1) becomes,

K.E= 1/2 (2000) (10)^2

= (0.5)(2000)(100)

= 100000

K.E = 100,000 Joules

The kinetic energy is 100,000 Joules, if a roller coaster of mass 2000 kg is rolling down a track with an instantaneous speed 10 m/s.

Answer:

72 km / hour

Explanation:

Speed equals to distance over time. We are given distance equal 360 km and time in 5 hours.

Hence:

[tex]\displaystyle \large{s=\frac{360}{5}}\\\displaystyle \large{s=72}[/tex]

Therefore, the speed is 72 km / hour.

Notes

Sometimes, speed is defined as ‘v’ while velocity is defined as ‘v vector’ indicating that velocity is speed with direction and speed is just velocity with only magnitude.

Explanation:

Answer:

B

Explanation:

A momentum does not stop it is conserved

C momentum is a vector quantity while energy is a scalar there is a difference

D momentum can't be formed a new it is still conserved

Answer:

3 m/s^2

Explanation:

Simply   F = ma

            15 = 5 a

             a = 3 m/s^2

Based on the length of the spring and the mass of the block, the distance the 4.0 kg block can fall before a reversal in direction is 32 cm.

Because energy is conserved, the distance the block can drop can be found as:

Mass x gravity x distance = (1 / 2) x spring constant x distance ²

Spring constant:

= (Mass x gravity)  / distance

= (3 x 9.8) / 12

= 2.45 cm

Distance is:

Mass x gravity x distance = (1 / 2) x spring constant x distance ²

distance = (2 x Mass x gravity) / spring constant

= (2 x 4 x 9.8) / 2.45

= 32 cm

Answer:

G M m / R^2      attraction of Jupiter to sun where m is mass of Jupiter

m V^2 / R      centripetal force acting on Jupiter

R = G M / V^2

The radius would be unchanged, and its orbit would be unchanged

Answer:

5N

Explanation:

Work done by a constant force is given by the following equation:

W=F⋅d⋅cos(θ)

where F is the applied force, d is the distance over which the force is applied, and θ is the angle between the force and displacement vectors.

In this case, the work is done by gravity, and as the object is assumed to fall straight down, θ=0^o.

We know that the force of gravity acting on an object can be expressed by FG=mg, and for an object which is not accelerating (e.g. a stationary object), this is equal to the object's weight.

We know d=10m,θ=0^o and W=50J, so we can solve for F to find the object's weight. ⇒F=Wdcos (θ) But cos (0^o)=1, so: F=Wd=50J10m=5N

Answer:

2 conduction

Explanation:

Answer:

2) conduction

Explanation:

Answer:

in the beginning the kinetic energy is at a maximum level because the starting velocity is high comparatively.. and because of the gravitational acceleration acting on the ball in the opposite direction the kinetic energy drops proportionally because of the velocity drop. after the ball reaches it's maximum height the potential energy of the ball is high because of the height.. and again the kinetic energy starts to build because the ball again starts to fall down..

Explanation:

The graph in the question that represents an object with constant acceleration is : Graph A

Acceleration is the change in velocity with time. For graph A the acceleration remained constant as the velocity of the object did not change with the change in time. As the time changes from 4 to 9 seconds the velocity of the object remained at 40 before decelerating to 0.  This shows that the acceleration of the object was constant.

Hence we can conclude that The graph that shows an object with constant acceleration is : Graph A

1. Using Strong Permanent. 2. increasing the current. 3. Decreasing the space between Magnets

Explanation:

Brainiest

The changes that make the motor stronger will be using strong permanent magnets, increasing the current, and decreasing the space between magnets.

An electric motor is a mechanism that turns electricity into mechanical energy.

The interaction between the motor's magnetic field and electric current in a wire winding generates force in the form of torque imparted to the motor's shaft in most electric motors.

An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.

When string magnets are used, a strong flux is produced, and the motor becomes more powerful. Internal flux has a significant impact on coil strength.

Increasing current results in greater power. In the same way, shortening the distance between magnets makes the motor stronger by increasing flux and torque.]

Hence the changes that make the motor stronger will be using strong permanent magnets, increasing the current, and decreasing the space between magnets.

Answer:

75 km/hour

Explanation:

Total distance travelled= 200+25 = 225 km
Total time= 2+1 hours = 3 hours
Average speed= Total Distance/Total time = 225/3 = 75 km/hr

The resultant wave of the different wave functions is = y1 + y2

The principle of superposition states that two waves moving through the same medium, the resultant value of the wave function is the sum of the different wave functions.

Waves superimpose by adding their disturbances,each disturbance corresponds to a force, and all the forces add.

Therefore, the resultant wave of the different wave functions is the addition of both wave functions which is = y1 + y2.
