Question

What is the kinetic energy of a toy truck with a mass of 0.75 kg and a velocity of 4 m/s

Answer 1

Answer:

The answer is 6 J

Explanation:

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

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

where

m is the mass

v is the velocity

From the question we have

$KE = \frac{1}{2} \times 0.75 \times {4}^{2} \\ = \frac{1}{2} \times 0.75 \times 16 \\ = 0.75 \times 8$

We have the final answer as

6 J

Hope this helps you
