Question

A man weighing 48kg carries a bag of 2kg he climbs to the top of a building 100m tall in 5min calculate the work done by the man and his power

Answer 1

given :
weight of the man = 70kg
weight of the thing carried = 10kg
height of the tower = 100m

need to find out :
the work done

solution :
total weight = 70+10 = 80kg
work done = mgh
= 80 * 10 * 100
= 80,000 J
therefore the work done = 80,000 J
