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

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 = 20 sec. If μs = 0.6, μk = 0.4, and θ = 25∘, determine the velocity v of the block at time t = 25 sec. Also, calculate the time t at which the block comes to rest again. (v = 89.4 ft/sec, the block never stops)
