1. The problem statement, all variables and given/known data Ike and Jim are sitting in toy trucks; the masses are 60kg and 40kg respectively. The trucks are moving at 8 metres per second along a track, with Ike's behind Jim's. Ike pushes Jim's truck away with a pole, and Jim moves off 2 metres per second faster than Ike. What is Jim's new speed? 2. Relevant equations Ft = mv - mu 3. The attempt at a solution I have tried using Conservation of Momentum and Newton Third's Law, but cannot seem to come to a correct solution. Thanks!
