A child in a tree house uses a rope attached to a basket to lift a 24 N dog upward through a distance of 5.0 m into the house.

Question

How much work does the child do in lifting the dog?

Express your answer to two significant figures and include the appropriate units.

Answer 1

Work done = Force* Displacement in the direction of force

Assuming force and displacement are in the same direction

Work = 24(N) * 5(m) = 120 Nm = 120 J
