A weightlifter that lifts two 300 newton weights 1.5 meters off the ground would have done 900 Joules of work.
Recall that:
work done = force x distance moved by the force
The weightlifter lifted two 300 newton weights,
Total force = 2 x 300
= 600 newtons
Distance = 1.5 meters
Hence:
Work done = 600 x 1.5
= 900 Nm or 900 Joules
