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.

A spring with a spring constant of k = 161 N/m is initially compressed by a block a distance d = 0.33 m from its unstretched length. The block is on a horizontal surface with coefficients of static and kinetic friction μs and μk and has a mass of m = 10 kg. Refer to the figure. Part (a) The block is released from the initial position and begins to move to the right. Enter an expression for the sum of the forces in the x-direction in the configuration shown above, in terms of defined quantities and g. Part (b) Calculate the smallest value for the coefficient of static friction μs that would keep the block from moving. Part (c) Assuming the block has just begun to move and the coefficient of kinetic friction is μk = 0.2, what is the block's acceleration in meters per second squared? a =
