Question

A motorcycle has 100,000 J of kinetic energy and is traveling at 20 m/s. Find its mass.

Answer 1

Answer:

The answer is 500 kg

Explanation:

The mass of the object can be found by using the formula

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

v is the velocity

KE is the kinetic energy

From the question we have

$m = \frac{2 \times 100000}{ {20}^{2} } = \frac{200000 }{400} = \frac{2000}{4}$

We have the final answer as

500 kg

Hope this helps you
