Question

Hi there! I'm currently stuck on the assignment I'm currently doing which was to analyse the physics behind bumper boats. So far I have (or planning to) use Rotational Kinetic Energy, Angular Moment

um, Centre of Mass, 2D Momentum but I just can't help but feel that i'm on the wrong track :/ How do you explain angular elastic collisions with bumper boats? Pleas help I honestly feel hopeless right now T_T Thanks!
