Question

What is the kinetic energy of an object with a mass of 10 kilograms traveling at a speed of 10 m/s? Assume no other forces act upon the object.

Answer 1

`=>500 " J"`

Explanation:

Kinetic energy is defined as:

`E = 1/2 m v^2`

where `m` is the mass and `v` is the speed.

Hence,

`E = 1/2 (10)(10)^2 = 500 " J"`
