How much work is done when 30.0kg crate is lifted 15.0m?

Answer 1

work = force * distance.

The force comes from the weight of the crate, equal to the mass of the crate (given as 30.0kg) multiplied by gravitational acceleration, 9.81m/s/s.

You are given the distance, 15.0m.

W = F*d
W = ?

Answer 2

the answer is 450j because work is always a product of displacement and force.
so
w=f*d
w=30.0*15.0
w=450joles

Answer 3

Note to the above response: 30.0kg is not the force.
