Question

Calculate the work done by a force of 30N in lifting a load of 2 Kg to a height of 10m(g = 10 ms^-1 )

Answer 1

Given:

F = 30 N, load (m) = 2 kg; height = 10 m, g 

= 10 ms^-2 

Gravitational force F = mg = 30 N 

The distance moved h = 10 m 

Work done on the object W = Fh = 30 × 10 = 300 J.
