Question

What is the kinetic energy of a ball with a mass 2.55 kg and a velocity of
3.81 m/sec?

Answer 1

18.51 J

Step-by-step explanation:

The kinetic energy of an object can be found by using the formula

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

m is the mass

v is the velocity

From the question we have

`k = (1)/(2) * 2.55 * {3.81}^(2) \\ = 1.275 * 14.5161 \\ = 18.5080275`

We have the final answer as

18.51 J

Hope this helps you
