Question

When a golf ball is hitit travels at a rate of 50 m/s . The mass of the golf ball is 0.045kg. What is the kinetic energy of the golf ball?

Answer 1

56.25 Joules

Step-by-step explanation:

The velocity (v) of the ball = 50 m/s

The mass of the ball = 0.045 kg

Formula for kinetic energy =
`(1)/(2)*m*v^2`

So the Kinetic enrgy =
`(1)/(2)*50^2*0.045 \\=1/2*112.25\\=56.25  Joules`
