A crate of mass 9.4 kg starts from rest and is pulled up a rough incline. The pulling force is 104 N parallel to the incline The incline makes an angle of 20.3° with the horizontal. The coefficient of kinetic friction is 0.400, and the crate is pulled 4.94 m up the incline. a. How much work is done by the 104-N force on the crate? b. How much work is done by the kinetic friction force? C. What is the speed of the crate after being pulled 4.94 m up the incline?

Problem 4: Speed deamplifier. In the figure above on the right, block 1 of mass m1 slides along an x-axis on a frictionless floor at speed 4 m/sec.Then it undergoes a one-dimensional elastic collision with stationary block 2 of mass m2 = 2m1. Next, block 2 undergoes a one-dimensional elastic collision with stationary block 3 of mass mz = 4m1. What then is the speed of block 3? Answer: 16 m/sec or 1.78 m/sec.
