A particle at the origin is experiencing three forces. The first one has a magnitude of 57 lb and is directed towards (2,-4,5), while the second one has a magnitude of 32 lb and is directed towards (-1,-2,-8). If the net force is 41 lb in the direction of (-5,-1,4), what is the x-component of the third force acting on the particle (in lb)?
The x-component of the third force acting on the particle is 41.2 lb.
The given parameters;
(2, -4, 5) = 57 lb(-1, -2, -8) = 32 lb(-5, -1, 4) = 41 lbThe vector components of the forces is calculated as;
[tex]F_1 = 57, (2,-4, 5) = 57\times \frac{2i -4j+ 5k}{\sqrt{2^2 + 4^2 + 5^2} } = 8.5(2i -4j+ 5k)\\\\F_1 = (17 i -34j + 42.5k)lb\\\\\\ F_2 = 32, (-1, -2, -8) = 32\times \frac{-i -2j-8k}{\sqrt{1^2 + 2^2 + 8^2} } = 8.3(-i-2j-8k)\\\\ F_2 = (-8.3i - 16.6j - 66.4k)lb\\\\\\ F_{net}= 41, (-5, -1, 4) = 41\times \frac{-5i -j+ 4k}{\sqrt{5^2 + 1^2 + 4^2} } = 6.5(-5i-j+ 4k)\\\\ F_{net} = (-32.5i -6.5j+ 24k)lb[/tex]
The x-component of the third force is calculated from the resultant of the forces;
[tex]F_1+F_2 + F_3 = F_{net}\\\\F_3 = F_{net} - (F_1 + F_2)\\\\F_3 = (-32.5i -6.5j + 24k) - (17i -34j + 42.5k) - (-8.3i -16.6j -66.4k)\\\\F_3 = (-32.5 -17 + 8.3)i +(-6.5 + 34+ 16.6)j + (24 -42.5+66.4)k\\\\F_3=(-41.2 i) +(44.1)j + (47.9)k\\\\F_3 = (-41.2i + 44.1 j + 47.9k)lb[/tex]
Thus, the x-component of the third force acting on the particle is 41.2 lb.

a.
neither
b.
westward
c.

d.
not enough information
Please solve step by step
Answer:
F = 1 N
Explanation:
F = Gm₁m₂/r² + kq₁q₂/r²
F = (Gm₁m₂ + kq₁q₂) / r²
F = [6.674(10⁻¹¹)(0.50)(0.25) + 8.988(10⁹(5(10⁻⁶))(-2(10⁻⁶))] / 0.30²
F = 0.9986666667593611111...
F = 1 N
notice that the electrostatic force by itself results in an attraction of
0.99866666666666666666... N
The gravitational force is quite negligible in this example.

A car starts from rest and accelerates at a steady 6.00 m/s2. How far does it travel in the first 3.00 s?
When a projectile reaches the highest point the vertical component of the acceleration is:
(A) Less than g (B) Greater than g (C) Positive g (D) Negative g
Answer:
The acceleration is g.
Taking the upward direction as positive
V = Vy y - 1/2 g t^2
Taking the downward direction as positive
V = -V y + 1/2 g t^2
One can choose either direction as positive, but the acceleration is
the same as g (it is g) while the projectile is in the air.
When a projectile reaches the highest point the vertical component of the acceleration is negative g (acceleration due to gravity). Thus, the correct option is D.
What is Projectile motion?Projectile motion is the motion of an object which is thrown or projected high into the air. After the initial force applied on the object that launches the object, the object only experiences the gravitational force. The object is called a projectile and the path of the object is called trajectory.
When a projectile reaches the highest point the vertical component of the acceleration is negative g (acceleration due to gravity). When the object achieves highest point, then the vertical acceleration of a projectile is zero meter per second square when it is at the peak of its trajectory motion.
Therefore, the correct option is D.

A baseball pitcher throws a fastball at a speed of 44 m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it through an almost straight-line distance of 3.5 m. Calculate the acceleration, assuming it is uniform. Compare this acceleration to the acceleration due to gravity.
v = s/t
44 m/s = 3.5 m/t
t = 3.5 m : 44 m/s
t = 0.08 s
a = v/t
a = 44 m/s/0.08 s
a = 550 m/s²
a : g = 550 m/s² : 10 m/s²
a : g = 55 : 1

In the Freebody diagram the magnitude of the normal force is 40 N, the friction force is 25N, the net force is 80N. what is the magnitude of the applied force?
Answer:
Explanation:
Without the FBD or a good description of the set up, I'd have to say we cannot tell.
If the set up is of the simplest form with a mass on a horizontal surface being acted on by a horizontal force, then that force must be 80 + 25 = 105 N.
As force is a vector, there are an infinite number of other possibilities for force magnitude depending on which direction the force is acting. The mass is also an unknown variable that would affect the applied force magnitude if the direction is not horizontal.

Both trains have the same speed and are approaching each other.
They both have to cover 8.5km, and since they are going the same speed they need to cover half the distance each (4.25km)
So, how long will it take a train going 155km/h to travel 4.25km?
The ratio of
[tex]\frac{155km}{1hour} = \frac{4.25km}{x hours}[/tex]There are 60 x 60 seconds in one hour (3600 seconds)
[tex]\frac{155km}{3600 seconds} = \frac{4.25km}{x seconds}[/tex]
Solve for x to get 98.7 seconds
We can do this by flipping both sides of the ratio
[tex]\frac{3600 s}{155 km} = \frac{x seconds}{4.25 km}[/tex]
Multiply both sides by 4.25km
4.25 × [tex]\frac{3600 s}{155 km} ={x seconds}[/tex]
Our unknown x = 98.7 seconds

The muscular system consists of exclusively this kind of tissue.
Answer:B
Explanation:
Each muscle or organ is composed of skeletal muscle tissue, connective tissue, nerve tissue, and blood or vascular tissue. Thus, the muscular system consists of all types of tissue.
What is the muscular system?The Muscle fibers are specialized cells that make up the muscular system. Its ability to contract is its main characteristic. Muscles that are attached to bones, internal organs, or blood arteries are what move things. Muscle contraction is the primary cause of almost all bodily movement. A skeletal muscle on its whole is a part of the muscular system.
Muscle cells, also known as muscle fibers or monocytes (mostly in skeletal and cardiac muscle), make up the majority of the organs that make up muscles (mainly in smooth muscle).
By contracting and pushing food to the small intestine through a process known as peristalsis, the muscles surrounding the stomach aid in the flow of food through the digestive system.
