6 meters if 120 J of energy was used?
Which has more kinetic energy, a 5 g bullet
moving at 100 m/s or a 1 kg baseball thrown at 10 m/s?
How fast was a 70 kg motorcycle moving
if it had 400 J of kinetic energy?
How high up is a 70 kg diver if he has
21,000 J of gravitational potential energy?
What is the elastic potential energy of
a bungee cord with a spring constant of 10 N/m that is stretched from its
normal resting length of 10 m to 17 m?
What is the power output of a car with
a mass of 1500 kg accelerating at a rate of 5 m/s2 over 20 meters for 3

water vapor, how long would it take for a 2.00 kW pump to raise the same
amount of water to the cloud’s altitude of 2.00 km?
