A small dog is trained to jump straight up a distance of 1.2 m. How much kinetic energy does the 7.2-kg dog need to jump this high? (The acceleration due to gravity is 9.8 m/s2.) Show your work for credit.

Answer 1

e = m g h = 7.2 * 9.8 * 1.2 (Joules)

Answer 2

how does that give you ke

Answer 3

the ke at the bottom equals the pe at the top

both measured in Joules
