Answer :
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
