Question

How to use kinetic energy to calculate velocity

Kinetic Energy: 150,000J

Mass: 120kg

Answer 1

As we know the formula of kinetic energy is

`KE = (1)/(2) mv^2`

here given that

KE = 150,000 J

mass = 120 kg

we can use this to find speed

`150,000 = (1)/(2) * 120 * v^2`

`v^2 = 2500`

`v = 50 m/s`

So speed of above object is 50 m/s
