What is the kinetic energy of 3500 kg bus that is moving at 25 m/s
Bond [772]

Answer:

<h2>1093750 J</h2>

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 3500 \times  {25}^{2}  \\  = 1750 \times 625 \\  = 1093750 \:  \:  \:  \:  \:

We have the final answer as

<h3>1,093,750 J</h3>
