Problem 1. In the system shown to the right, an inextensible cable that passes around pulleys, such as the one from which block B hangs, connects the three blocks. Blocks A and C move with velocities and accelerations shown parallel to the blue planes. Find (a) the acceleration and velocity of block B, (b) the velocity of block A relative to block C, and (c) the acceleration of block B relative to block A.

Problem 2. Cars move along the two adjacent roads shown. At the instant depicted, Car A moves along the circular road at a speed of 60mph which is decreasing at 6480 miles/hr² while car B moves at a constant speed of 75mph along the straight road.

The circular road has radius r = 500 ft. Determine the velocity and acceleration of Car A relative to Car B.
