Question

What is power? Show that power is f*v? Calculate power of a body of mass 10kg accelerating with 10m/s2 acquires a velocity of 5m/s?(?

Answer 1

We know that Power is Energy per unit time

P = E/t

P = Fd/t. d is distance travelled with that

force in time t

P = F.v d/t = v,. velocity

Now for the numerical

P = Fv = mav. F = ma

P = 10.10.5

P = 500 watt
