1. A car of mass 800kg is at rest. The engine exerts a resultant force of 2000 N for a distance of 5m. a) What is then its kinetic energy? b) What is then its speed? 2. It is required that you must not use any SUVAT equations while solving this problem. Possible equations to use are: kinetic energy = 1/2 x m x v^2 Gravitational Potential Energy = m x g x h Work = force x distance F = m x a W = m x g 3. I have attempted this question a number of times as I'm trying to find the velocity, but since there is no height in this question, I can't use the GPE equation, I'm just a little bit confused and would really appreciate some help.
