Question: A 1000g model rocket is resting horizontally at the top edge of a 40-m-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.
Part A: How far from the base of the wall does the rocket land?
I need help to find how far from the base of the wall does the rocket land.
