The 100-lb block is stationary at time t = 0, and then it is subjected to the force P shown. Note that the force is zero for all times beyond t = 18 sec. Determine the velocity v of the block at time t = 18 sec. Also calculate the time tat which the block again comes to rest. Answers: At t = 18 sec, v = ft/sec Comes to rest at t = sec

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.
