Question

8) Calculate the kinetic energy of a truck that has a mass of 6100 kg and is moving at 55 m/s.

Answer 1

Answer:

9,226,250 J

Explanation:

The kinetic energy of an object can be found by using the formula

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

v is the velocity

m is the mass

From the question we have

$k = \frac{1}{2} \times 6100 \times {55}^{2} \\ = 3050 \times 3025 \\ = 9226250$

We have the final answer as

9,226,250 J

Hope this helps you
