Calculating Velocity from Kinetic Energy: A Homework Problem Solution"

[huskiehenne]

Homework Statement

A car witha mass of 1500 kg has a Kinetic Energy of 1,400,000 Joules. What is its velocity?

Homework Equations

I would assume that (K.E.=1/2 x m x v 2) could be used.

The Attempt at a Solution

I am not exactly sure how to attempt this question. Do we try to make velocity by itself in the above equation? I am not quite sure how to go about that...

Yes, that's how you solve for v, isn't it?
