Question

A large piece of wood is at rest on a horizontal floor. The coefficient of kinetic friction between the wood and the floor is 0.220. A bullet with mass 9.7 g is fired
horizontally into the piece of wood, which has a mass of 10.9 kg, and becomes embedded in the wood. The bullet's speed before the impact is 900 m/s. Find
how far the wood will slide before coming to stop.

A woman weighing 57.1 kg stands at one end of a 120-kg raft that is 6.00 m long. The other end of the raft is 0.500 m from a pier. So, before the woman moves, she is at a total distance of 6.50 m away from the pier. The woman walks toward the pier until she gets to the other end of the uniform raft and stops there. What is the distance between the uniform raft and the pier?

10. A snowboarder starts at the top of a 160. m tall hill with a velocity of 3.00 m/s. The portion of the hill covered with snow is essentially frictionless, but the flat, horizontal section at the base of the hill covered with mud is not. If the snowboarder masses in at 80.0 kg, and the coefficient of kinetic friction between board and mud is 0.750, how much distance is required for the snowboarder to come to rest?
The 1-kg ball is thrown at the suspended 10-kg block with a velocity of 4 m/s. If the coefficient of restitution between the ball and the block is e=0.8, determine the maximum height h to which the block will swing before it momentarily stops. 4 m/s В h A
1. The 10-lb block has a speed of 4 ft/s when the force of F = (8t?) Ib is applied. Determine the velocity of the block when it moves s = 20 ft. The coefficient of kinetic friction at the surface is Uz = 0.15. Note: It's okay to use an online equation solver to calculate a number in this problem! v = 4 ft/s F = (8f) lb
9. A 1200 kg car drives at an initial velocity vo = 45 m/s along a highway. At t = 0, the driver releases the gas, and the car slows to a stop due to a drag force given by Fdrag = -b v, where b = 15 kg/s³. Derive a function for the car's velocity as a function of time and solve it for the car's velocity at 10, 20, and 30 s.
