Question

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

Answer 1

The answer is 500 kg

Step-by-step 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 * 100000}{ {20}^(2) } = (200000 )/(400) = (2000)/(4) \\`

We have the final answer as

500 kg

Hope this helps you
