Question

A 40.0-kg package on a the roller belt conveyor is moving at 0.600 m/s. What is

its kinetic energy? *
O 7.2 J
O 12 J
O 14.4 J
O 0J
O24J

Answer 1

Its A ! Hope this helped

Answer 2

7.2 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) * 40 * {0.6}^(2) \\ = 20 * 0.36 \\ = 7.2`

We have the final answer as

7.2 J

Hope this helps you
