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

150 joules.

Explanation:

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

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

= 150 J.

Answer 2

Answer: 150 Kg
`m^(2)`/
`s^(2)`

Explanation:

K.E =
`(1)/(2)`m
`v^(2)`

K.E =
`(1)/(2)` X 12 X 25

K.E = 150
