7. The 20-kg crate is subjected to a force having a constant direction and a magnitude F = 100 N. When s= 15 m, the crate is moving to the right with a speed of 8 m/s. Determine its speed when s= 25 m. The coefficient of kinetic friction between the crate and the ground is H=0.25. The block shown was initially at rest on the plane. A force P = 500 N is applied on 30°

A baseball catcher is performing a stunt for a television commercial. He will catch a baseball (mass 145 g) dropped from a height of 60.0 m above his glove. His glove stops the ball in 0.0100 s. What is the force exerted by his glove on the ball?
A person doing a chin-up weighs 700 N, exclusive of the arms. During the first 25.0 cm of the lift, each arm exerts an upward force of 355 N on the torso. If the upward movement starts from rest, what is the persons velocity at that point?
Consider Figure 5.28. The driver attempts to get the car out of the mud by exerting a perpendicular force of 610.0 N, and the distance she pushes in the middle of the rope is 1.00 m while she stands 6.00 m away from the car on the left and 6.00 m away from the tree on the right. What is the tension Tin the rope, and how do you find the answer?
