A block of weight W = 200 N on an incline of 20∘ with respect to the horizontal direction is subjected to a constant force P that is inclined by an angle of 30∘ with respect to the horizontal direction, as shown in Figure 3. The coefficients of static and kinetic friction between the block and the incline are μs = 0.30 and μk = 0.20, respectively. a) Draw a free body diagram of the block and find the maximum force P = Pmax that can be applied before the block starts to slide up the incline. Find the normal force N exerted by the incline on the block when P = Pmax . b) For a force P = 500 N, draw a free body diagram of the block and find its (constant) acceleration a up the incline. c) If the block starts from rest at time t = 0 when the force P = 500 N is first applied to the block, find the speed v = v(t) of block and the distance s = s(t) it travels up the incline at any time t.

3. (18 pts) In the diagram below, a block (m2 = 1.5 kg) is at rest on the right edge of a large slab (m1 = 9.0 kg). There is a coefficient of kinetic friction between m1 and m2 equal to 0.2. The slab, in turn, is sitting on a slippery floor with effectively zero friction (μk = 0). The slab is 4.0 meters wide, and the block is 0.5 meters wide. A constant horizontal force F→ is applied to the block, pulling it to the left. It takes two seconds for the block to reach the other side of the slab. (a) How far (in meters) is the bottom slab pulled along in that time? (b) What is the magnitude of F→? *Hint: The block starts with its right side lined up with the right side of the slab, and ends up with its left side lined up with the left side of the slab. Determine an expression for the distance the slab moves in terms of how far the block moves. Use an inertial reference frame, i. e. static origin on the right side of the table.

A 20.0 kg crate is subjected to a constant force of 100 N as shown in the figure. When the distance it is pulled is s = 15.0 m the crate is moving at 8.0 m/s. Determine its speed when s = 25 m. The coefficient of kinetic friction between the crate and the ground is 0.25 . Use the principle of work and energy.
