Question

What is the kinetic energy of an object that has a mass of 50.0 kg and a velocity of 18 m/s?

450 J
900 J
8,100 J
16,000 J

Answer 1

Answer: 8,100 J

Explanation: Edge

Answer 2

The answer is 8,100 J

Step-by-step explanation:

The kinetic energy of a body when given it's mass and velocity can be found by using the formula

`KE = (1)/(2) m {v}^(2)`

where

m is the mass

v is the velocity

From the question

mass of object = 50 kg

velocity = 18 m/s

It's kinetic energy is

`KE = (1)/(2) * 50 * {18}^(2) \\ = 25 * 324`

We have the final answer as

8100 J
