Homework Statement
Movers must push a piano onto a truck, the bed of which is a height 1.35 m above the ground. To do this they will use a frictionless ramp. If the piano has a mass of 1806.0 kg and the movers push it up the slope at a constant velocity, how much work do they need to do on it to move it into the bed? Please provide your answer in kilo-Joules (kJ), as the amount of work should be quite large
Homework Equations
I know it involves kinetic and potential energy
K = (1/2)mv2
U = mgh
The Attempt at a Solution
I'm not sure how to calculate the velocity
