A 1500 g model rocket is resting horizontally at the top edge of a 40m-high wall when it is accidentally bumped. The bump pushes it off the edge with a horizontal speed of 0.5 m/s and at the same time causes the engine to ignite. When the engine fires, it exerts a constant 20 N horizontal thrust away from the wall. How far from the base of the wall does the rocket land?
