Answer:
(a) as you know, work done = mass × acceleration due to gravity × height
for both cases, height is same.
load , m = 15kg for both cases.
hence, work done must be same.
so, workdone by Monty = workdone by pintu
(b) power = workdone/time,
e.g., power is inversely proportional to time taken .
here, Monty takes time = 2 min
so, Power of Monty = W/2
and pintu takes time = 1.5 min
so, power of Pintu = W/1.5
so, it is clear that power of Pintu is greater than power of Monty
