Question

a person of mass 50kg climbs a tower of ght 72m calculate work done in 1 hour

Answer 1

u haven't given any relation with the time it take to climb and it must be given I need the question itself whereas in all these types of question we have to go in terms of potential energy suppose a man move 50 m up weighing 50kg then work done will be mgh 50×50×10 where's if time given for example a man climbs 50 m in 30 min then work done in 1 hour will be mgh×2 hope u understand
