Question

A car with a mass of 650kg is moving with a speed of 22m/s calculate the kinetic energy of the car.

Answer 1

Answer:

157,300 J

Explanation:

The kinetic energy of the car can be found by using the formula

$k = \frac{1}{2} m {v}^{2}$

m is the mass

v is the velocity

From the question we have

$k = \frac{1}{2 } \times 650 \times {22}^{2} \\ = 325 \times 484$

We have the final answer as

157,300 J

Hope this helps you
