On a warm day, a climber does 3,000 joules of work pulling himself up a mountain. If he weighs 500 Newton's, how high does he climb?

Answer: 6 metres

Explanation:

Work is done when force is applied by the climber over a distance.

i. e Workdone = Force x Distance

Since, Workdone = 3,000 joules

Force = 500 Newton

Height climbed = ?

Then, Workdone = Force x Distance

3000J = 500N x Distance

Distance = (3000J / 500N)

Distance = 6 metres

Thus, the climber went 6metres high
