Question

A 10 gram ball is rolling at 3 m/s. What is the energy the ball has?

Answer 1

K = 0.045 J

Step-by-step explanation:

It is given that,

Mass of a ball, m = 10 g = 0.01 kg

Speed of the ball, v = 3 m/s

To find,

The energy of the ball.

Solution,

Due to the motion of the ball, it will have kinetic energy. It can be given by the formula as follows :

`K=(1)/(2)mv^2\\\\K=(1)/(2)* 0.01* 3^2\\\\K=0.045\ J`

So, the ball will have a kinetic energy of 0.045 J.
