monty takes 2 minutes to raise a load of 15 kg from the ground to 3rd floor of a building.pintu takes 1.5 minutes to complete the same job
compare -a) the work done
b) powers of monty and pintu

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
