PS3-2 #8 A baseball pitcher pitches a baseball. If the pitcher wanted to decrease the amount of kinetic energy the ball had when it made contact with the bat, what could the pitcher change?

PS3-2 #9 A student is investigating potential and kinetic energy by stretching an elastic hair tie. When the student lets go, the elastic hair tie is flung across the classroom. At which time is potential energy in the spring being converted into kinetic energy?

PS3-2 #10 Which picture shows the spring when it has the most potential energy?

PS3-2 #11 Two cars are driving down a hill. One car is full of passengers, so it has a lot of mass but the other only has the driver.
