Question

Calculate the kinetic energy of a truck that has a mass of 2900 kg and is moving at 15 ms

Answer 1

Answer:

326,250 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

$k = \frac{1}{2} \times 2900 \times {15}^{2} \\ = 1450 \times 225 \\ = 326250$

We have the final answer as

326,250 J

Hope this helps you
