Question

A ball of mass 400g rolls on a ground with a uniform speed a 25m/s.Find the kinetic energy possessed by it.

Answer 1

the kinetic energy posses is8

Answer 2

Hi.

Here is your answer--------------

Given----

Mass of the ball(m) = 400 grams
                               = 4/10 kg.

Velocity of the ball(v) = 25 m/s.

Using the formula,
                          K = (1/2 )mv^2
                          K = (1/2) 0.4 x 25 x 25
                          k = 125 Joules.

Thus, kinetic energy will be 125 Joules.

Hope it helps.

Have a nice day.
