A 100 Kg man is holding a 25 Kg mass at 3 M above the ground. What is the potential energy of the mass? If the man, and the mass were catapulted at a speed of 15 m/s, what would be the kinetic energy of the man/mass combo?
PE = mgh
g = acceleration due to gravity 9.8 m/s2 (squared)
KE = 1/2(mv2) you can't do superscript on Blogger! (mass x velocity squared)
