(b) A person carrying 10 bricks, each of mass 2.5 Kg on his head moves to a height of 20 meter in 50 Seconds. Calculate the power spent in carrying bricks by the person? (g=10 m/s2)
work done =mass x gravitation x height
W=2.5x10x20 Joules
W=500 Joules
power=Work Done/Time
P=500/50
P=10 Watt
i hope dis wud help u Simran
