1. The problem statement, all variables and given/known data

Calculate how much work is done when a 1150 kg car accelerates from 2 m/s to 6m/s

2. Relevant equations



3. The attempt at a solution

I have no idea. It seems like insufficient information to me. Please help! I am in great need as my exam is drawing near!

Thanks!

Work done=change in KE=0.5*1150(6^2-3^2)
