Calculating Velocity from Kinetic Energy: A Homework Problem Solution"

Click For Summary
SUMMARY

The discussion focuses on calculating the velocity of a car with a mass of 1500 kg and a kinetic energy of 1,400,000 Joules using the equation K.E. = 1/2 x m x v². The correct approach involves rearranging the equation to isolate velocity (v). By substituting the known values into the equation and solving for v, the final velocity can be determined definitively.

PREREQUISITES
  • Understanding of kinetic energy concepts
  • Familiarity with algebraic manipulation

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?
