Question

A man pulls a bucket of water of mass 10 kg from a well 5m deep in 5sec calculate the power

Answer 1

HEYA...

HOPE ITS HELPFUL


M= 10 KG

H= 5 M

THEREFORE POWER= WORKDONE PER UNIT TIME

LET g-= 10 M/S^2

= M G H/ T

= 10 * 5 * 10/ 5

=100

THEREFORE POWER = 100 WATT

Answer 2

work = mass × displacement
= 10×5
= 50kg/m
= 500g/cm

power= work done÷time
= 500÷5
= 100W

hope it help
