Answer: 4 metres
Explanation:
Work done by climber = 8 J
Force applied on object = 2 N
Distance = ?
Recall that work is done when force is applied on an object over a distance.
i.e Workdone = Force x distance
8J = 2N x distance
distance = 8J/2N
distance = 4m
Thus, the object is lifted by a distance of 4 metres
