Question

A mass of 15 kilograms and is running on the ground with a velocity of 2.7 meters per second. What is the kinetic energy

Answer 1

Answer:

54.68 J

Explanation:

The kinetic energy of an object 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

$k = \frac{1}{2} \times 15 \times {2.7}^{2} \\ = 7.5 \times 7.29 \\ = 54.675$

We have the final answer as

54.68 J

Hope this helps you
