Question

Find the mass of a car that is travelling at a velocity of 60 m/s North. The car has 6, 025, 000 J of kinetic energy.

Answer 1

For this problem, lets use the kinetic energy formula

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

Where m is equal to mass and v is equal to velocity

In our given, we have:

velocity = 60 m/s

kinetic energy = 6,025,000 J

Plug these numbers into the formula to get the mass

`6,025,000=(1)/(2)m(60)^2`
`(6025000)/(60^2)=(1)/(2)m`
`1673.611=(1)/(2)m`

m = 3347.222 kg
