a moving company tries to load a 143 kg antique chest onto a truck bed which is 1m off the ground. they use a 4m long ramp. how much work do they have to do?
if anyone could explain the steps to solve this problem. please and thanks

The length of the ramp is irrelevant. The total work done is the weight of the chest multiplied by the vertical distance, that is
W = 143 kg * 9.8 m/s^2 * 1m = 1401.4 J
In practice, the work done might be more due to inefficiencies such as friction.
