Question

A RICKSHAW PULLER PULLS THE RICKSHAW BY APPLYING A FORCE OF 100 N. IF THE RICKSHAW MOVES WITH A CONSTANT VELOCITY OF 36 km/h , FIND THE POWER OF THE RICKSHAW PULLER

Answer 1

Here,

F = 100N

v = 36 kmph

= 10 m/s

P = ?

We know

P = W/t

Again W = Fd

=> P = Fd/t

=> P = Fv

Now power = Fv

= 100×10 = 1000 W or 1 kw
