Question

A body having 200 gram is moving with velocity of 120 m/s. What is its power?

Answer 1

hey its answer i hope its good

Answer 2

Explanation:

K.E of the body = 1/2*0.2*(120)²= 1440 J

Here time is not given. we know amount of work done per unit time is called power. So, if the body posesses 1440J kinetic energy per unit time then the work done by the body per unit time is 1440J. So, the power of the body is 1440 watt.
