Question

Hi, I need help with this problem I know that I need to thinkabout the kinetic energy to solve it, but I am not sure on how toset it up. I would really appreciate any help?
Problem: A car at 30 miles per hour skids 40 feet with lockedbrakes. How far will the car skid with locked brakes at 90miles per hour? (hint: think about Kinetic Energy) Hi, I need help with this problem I know that I need to thinkabout the kinetic energy to solve it, but I am not sure on how toset it up.

Explanation / Answer

A car at 30 miles per hour skids 40 feet with locked brakes. How far will the car skid with locked brakes at 90 miles per hour?(hint: think about Kinetic Energy) kinetic energy=breaking force*distance so stopping distance is proportional to kineticenergy ke1/ke2=d1/d2 d2=40*90*90/30*30=360feet
