1. Homework Statement
A 2.0 kg mass is fired straight up with a intial velocity of 60.0m/s
A) wat is the kinetic energy when its 20.0m above the ground
B)wat is the changhein height when its speed changes from 50m/s to 40m/s
2. Homework Equations
Ek=mv2/s
3. The Attempt at a Solution
A)EK=mv2/2 B)i didnt get question B
=2.0kg*60.0ms
=3600J
