KINETIC ENERGY PRACTICE 1) Measures and their (Units) Identify the unit (label that goes with each measurement) energy _____________ weight _______________ (not pounds) mass _____________ speed _______________ 2) You serve a volleyball that has a mass of 2.1 kg. The ball leaves your hand with a speed of 30 m/s. How much kinetic energy does the volleyball have? 3) What is the kinetic energy of a car that is traveling with a speed of 40 m/s and has a mass of 1120 kg? 4) A 3 kilogram ball is rolling at 2 meters per second? How much kinetic energy does the ball have? 5) How much kinetic energy does a roller coaster have if its mass is 3,000 kg and is moving at 30 m/s? 6) You throw a 0.15 kg baseball to the first baseman. The ball travels with a speed of 36 m/s. How much kinetic energy does it have? 7) What kinetic energy has a 4 kg shotput thrown with a speed of 13 m/s? 8) A train and a car are both traveling at 60 miles per hour. How does the kinetic energy of these two compare? Explain your answer. 9) Sam is at the skate park. He has a mass of 22 kg and a speed of 7 m/s as he moves up a quarter pipe. What is his kinetic energy?
10) Calculate the kinetic energy of the bungee jumper.
