Question

Determine the Kinetic Energy of Joe's car with a mass of 1500 kg and a

rate of 40 m/s.

A.2.1 x 10^6

B.1.2 x 10^6

C.3.0 x 10^6

D.1.2 x 10^5

Answer 1

C

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) * 1500 * {40}^(2) \\ = 750 * 400 \\ = 300000 \\ \\ \\ \\ = 3.0 * {10}^(6) \: \: joules`

Hope this helps you
