1. A 5,100-kg truck runs into the rear of a 1,000-kg car that was stationary. The truck and car are locked together after the collision and move with speed 6 m/s. What was the speed of the truck before the collision?


________


2. In compressing the spring in a toy dart gun, 0.4 J of work is done. When the gun is fired, the spring gives its potential energy to a dart with a mass of 0.04 kg.


(a) What is the dart's kinetic energy as it leaves the gun?


_________


(b) What is the dart's speed?


_________


3. At NASA's Zero Gravity Research Facility in Cleveland, Ohio, experimental payloads fall freely from rest in an evacuated vertical shaft through a distance of 132 m.


(a) If a particular payload has a mass of 19 kg, what is its potential energy relative to the bottom of the shaft?


_________


(b) How fast will the payload be traveling when it reaches the bottom of the shaft?


_________


Convert your answer to mph for a comparison to highway speeds.


_________




4. A bicycle and rider going 15 m/s approach a hill. Their total mass is 85 kg.


(a) What is their kinetic energy?


_________


(b) If the rider coasts up the hill without pedaling, how high above its starting level will the bicycle be when it finally rolls to a stop?

5. A 1,000-W motor powers a hoist used to lift cars at a service station.


(a) How much time would it take to raise a 2,350-kg car 2 m?


_________


(b) If the original motor is replaced with one rated at 3,000 W, how long would it take to complete this task?



__________


6. A running back with a mass of 88 kg and a velocity of 9 m/s (toward the right) collides with, and is held by, a 132-kg defensive tackle going in the opposite direction (toward the left). What is the velocity of the tackle before the collision for their velocity afterward to be zero? (Remember, velocity is a vector)


________________


7. An elevator is able to raise 9,800 N to a height of 27 m in 17 s.


(a) How much work does the elevator do?


_________


(b) What is the elevator's power output?
