## Homework Statement

A car and a truck have the same kinetic energy, but the car's mass is one fifth that of the truck. Compare the velocity and momentum of the car with those of the truck.

## Homework Equations

KE=1/2mv^2

p=mv

## The Attempt at a Solution

I am not really sure what to do here. I tried setting up the Kinetic energy equal to each other, but then the mass and velocity would cancel each other out an I am left with 1/2=1/10. My other method was subtracting the 2 energys, but that doesn't make sense now that im thinking about it...

Any tips on how to do this?
