the time taken , t = 1.052 s
initial velocity , u = 0 m/s
the height from which the ball is dropped , H = 0 + 0.5 * g * t^2
H = 0 + 0.5 * 9.81 * 1.052^2 m
H = 5.43 m
the height is 5.43 m

Learning Goal: To practice Problem-Solving Strategy 9.1 A strategy for conservation of momentum problems. An 80-kg quarterback jumps straight up in the air right before throwing a 0.43-kg football horizontally at 15 m/s . How fast will he be moving backward just after releasing the ball? Part F Suppose that the quarterback takes 0.30 s to return to the ground after throwing the ball. How far d will he move horizontally, assuming his speed is constant? Answer in meters.
