Unformatted text preview: C. The truck slows at a constant rate and reaches point D at the same time that the car reaches point B. Points B and D are at the same Y position. • How long does it take the car to travel from A to B? • What is the velocity of the truck at point D? • What is the velocity of the car at point B with respect to the truck at point D? • What is the acceleration of the car at point B with respect to the truck at point D? B A 3. Two masses A and B are arranged with pulleys as shown on the left. Mass A has an initial velocity (t=0s) to the left of 1.2 m/s. Mass B has a constant acceleration of 0.4 m/s 2 down. • What are the velocities of the blocks after 3 seconds? • How far has block B traveled from t=0s to t=3s?
