The car C and its contents have a weight of 530 lb , whereas block B has a weight of 230 lb . The car is released from rest. (Figure 1) Determine the car's speed when it travels 30 ft down the 20∘ incline. Suggestion: To measure the gravitational potential energy, establish separate datums at the initial elevations of B and C. Express your answer to three significant figures and include the appropriate units.
