Unformatted text preview: point B along a turn of radius r C =400 ft. The truck remains on the highway with a speed of 60 ft/s at point C. The truck accelerates at 2 ft/s 2 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 truck to travel from C to D? • What is the velocity of the car at point B? • 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 right of 1.2 m/s. Mass B has a constant acceleration of 0.6 m/s 2 down. • What are the velocities of the blocks after 4 seconds? • How far has block B traveled from t=0s to t=4s?
