Three boxes are connected in a sequence and accelerated in the positive x-direction as shown in the figure. Compare the magnitudes of the tension in the lines. T1 > T3 > T2 T1 > T2 > T3 T2 > T3 > T1 ...

A tennis ball is dropped at a speed of 32m/s, and a mass of 0.084KG. The tennis ball travels .010 seconds before stopping at a wall. Calculate average force by raquet on ball, and force of ball on raquet.

K basically this is F = Ma right? Isn't this law impractical for any situation outside of a vacuum? If I was pushing a toy car with a constant force 10N in order to make it accelerate, resistive forces would build up to oppose the resultant force and give it uniform motion. Therefore I would...

each of the four wheels of a car pushes on the road with a force of 4.0 x 10^3 N. The driving force on the car is 8.0 x 10^3N. The frictional resistance on the car is 6.0 x 10^3N . Calculate the following a) the mass of the car b) the net force on the car c) the car's acceleration. so...

Give an example of each of Newton's 3 Laws of motion (not the Law of Gravity)
