Two automobiles A and B are approaching each other in adjacent highway lanes. At t= 0, A and B are 3200 ft apart, their speeds are VA = 65 mi/h and VB = 40 mi/h, and they are at points P and Q , respectively. Knowing that A passes point Q 40 s after B was there and that B passes point P 42 s after A was there, determine (a ) the uniform accelerations of A and B,(b) when the vehicles pass each other, (c) the speed of B at that time.
Collar A starts from rest at t= 0 and moves downward with a constant acceleration of 7 in./s2. Collar B moves upward with a constant acceleration, and its initial velocity is 8 in./s. Knowing that collar B moves through 20 in. between t= 0 and t= 2 s, determine (a) the accelerations of collar B and block C, (b) the time at which the velocity of block C is zero, (c ) the distance through which block C will have moved at that time.
Block C starts from rest and moves downward with a constant acceleration. Knowing that after 10 s the velocity of block A is 465 mm/s, determine
