A 600g model rocket is on a cart that is rolling to the right at a speed of 4.5m/s . The rocket engine, when it is fired, exerts an 7.0N thrust on the rocket. Your goal is to have the rocket pass through a small horizontal hoop that is 25m above the launch point.
At what horizontal distance left of the loop should you launch?
