Question

How much kinetic energy is possessed by a 12 kg remote controlled car that is traveling with a speed of 5 m/s?

Answer 1

Answer: 150 Kg$m^{2}$/$s^{2}$

Step-by-step explanation:

K.E = $\frac{1}{2}$m$v^{2}$

K.E =  $\frac{1}{2}$ X 12 X 25

K.E = 150

Answer 2

Answer:

150 joules.

Step-by-step explanation:

Kinetic Energy of a moving object = 1/2 m v^2.

So it is 1/2 * 12 * 5^2

= 150 J.
