Acrate weighing 1000 newton's needs to be lifted at a constant speed from the ground to a loading dock 1.5 meters high in 5.0 seconds. what power is required to lift the crate?

the Power required is 300 W

Explanation:

We know that the definition of work is given by the following expresion:

the distance is 1.5 meters and the Force is equal to 1000 N.

Replacing this values in the work expresion

And the power is equal to the amount of work done in a given time, therefore we have:

Time in seconds

conservation of mass

mass before something happens = mass afterwards
