A 500 gram model rocket is resting horizontally at the top edge of a 40 meter 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 similar time causes the engine to ignite. When the engine fires, it exerts a constant 20 N horizontal thrust away from the wall.
(a) Determine how far from the base of the wall does the rocket land?
(b) Explain the trajectory of rocket while it travels to the ground.
