Question

A body of mass 10 kg climb up 10 steps each of the height 0.2 in 20 second calculate the power of the boy

Answer 1

ANSWER:

Mass of the body(m) = 10 kg

Force (F) = mg = 10 × 10 = 100 N

No. of steps = 10

height of each step = 0.2 m

therefore,

height obtained by the body(h) = 10 × 0.2

= 2 m

time(t) = 20 seconds

Work done(W) = 100 N × 2 m

W = 200 Nm

Now,

Power = W / t

= 200Nm / 20 sec

= 4000 W
