Question

What is the kinetic energy of a 3.6 kg bowling ball that moves with a velocity of 5 m/s?

Answer 1

The bowling ball has a kinetic energy of `9 J.`

Explanation:

To answer this question, we have to make use of the formula below:

Additionally, the kinetic energy will have units of `kgxxm^(2)/s^(2)`, which is the same as Joules, J.

We already have the mass and velocity, and both have the correct units so all we have to do is plug the given values into the equation:

`KE =(1/2)(3.6kg)(5m/s)^(2)`
`KE = 9kgxxm^(2)/s^(2)`

`KE = 9J`
