The car C and its contents have a weight of 620 lb, whereas block B has a weight of 290 lb. The car is released from rest. (Figure 1) Part A 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.
