Problem 12.2 A 125 lb block initially at rest is acted upon by a force P which varies as shown. Knowing that the coefficients of friction between the block and the horizontal surface are μs=0.50 and μk = 0.40, determine, (a) the time at which the block will start moving (b) the maximum velocity reached by the block P (lbf) 100 0 8 16 125 lb Time (s) Ans: a) 4 s≤tstart ≤ 5s b) 49 ft/s ≤ Vmax ≤ 51 ft/s
