Question

What is the kinetic energy of a 0.50 kg ball traveling at a speed of 120 m/s?

Answer 1

The answer is 3600 J

Step-by-step explanation:

The kinetic energy (KE) of an object given it's mass and velocity can be found by using the formula

`KE = (1)/(2) m {v}^(2) \\`

where

m is the mass of the object

v is the velocity

From the question

m = 0.5 kg

v = 120 m/s

So we have

`KE = (1)/(2) * 0.5 * {120}^(2) \\ = (1)/(4) * 14400`

We have the final answer as

3600 J
