Question

What is the kinetic energy of a 25 kg object moving at a velocity of 2.5 m/s?

Answer 1

Answer:

78.13 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

$k = \frac{1}{2} \times 25 \times {2.5}^{2} \\ = 12.5 \times 6.25 \\ = 78.125 \: \: \: \: \: \: \: \:$

We have the final answer as

78.13 J

Hope this helps you
