Answer:

1.08 x 10^-4 J

Explanation:

mass of ball, m = 0.3 kg

Velocity of ball, v = 96.6 m/hr

First convert m/hr into m/s.

As we know that 1 hour = 3600 second

So, 96.6 m / hr = 96.6 / 3600 m/s = 0.0268 m/s

The formula for the kinetic energy is given by

Kinetic energy = 1/2 mv^2

Kinetic energy = 0.5 x 0.3 x 0.0268 x 0.0268 = 1.08 x 10^-4 J
