So I'm about to prepare for a midterm. We have access to old midterms bu not the answers and I'm havign trouble wiht a problem. I've attached a copy since it contains a diagram. I don't know why, but my initial thinking is that the two side squares will travel in a straight line with half the initial speed of the ball and the middle cube will sit there with its point just touchign the ball (both at rest) anyone care to provide some insight and help solve this for me? Thanks!
