1. The problem statement, all variables and given/known data A 3.0 kg object travels vertically at a constant speed of 2.0m/s. What is the increase in gravitational potential energy after 4.0 sec? 2. Relevant equations Ep=Mgh 3. The attempt at a solution I know i need to find the height but, with constant velocity i dont know how to plug into any kinematic equations to find the height. The answer is 2.4 x 10^2 J.
