Question

How much kinetic energy does a moving 100 kg object have if it is moving at 5 m/s?

Answer 1

The object has 1250 Joules of Kinetic Energy.

Step-by-step explanation:

Kinetic Energy =
`(1)/(2)`mass*velocity²

KE =
`(1)/(2)`mv²

KE =
`(1)/(2)`(100kg)(5m/s)²

KE =
`(1)/(2)`(100kg)(25m/s²)

KE = 1250
`(kg)/(m/s^2)`

KE = 1250J
