(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A car of mass 2 (metric) tonnes is traveling at 20m/s. caculate its kinetic energy (can and have done) and the force required to stop it in 10 s.

2. Relevant equations

3. The attempt at a solution

I have found the KE = 4 *10^5 but i cant figure out how to calculate the force required to stop it in 10s. I think the equation for this mite be E/t=FV

The answer is 4*10^3N
