Question

What is the kinetic energy of a 100 kg bear running at 3 m/s

Answer 1

Answer:

The answer is 450 J

Explanation:

The kinetic energy of a body 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

m = 100 kg

v = 3 m/s

We have

$KE = \frac{1}{2} \times 100 \times {3}^{2} \\ = 50 \times 9$

We have the final answer as

450 J
