Small-plane pilots regularly compete in “message drop” competitions, dropping heavy weights (for which air resistance can be ignored) from their low-flying planes and scoring points for having the weights land close to a target. A plane 60 m above the ground is flying directly toward a target at 45 m/s. a. At what distance from the target should the pilot drop the weight? b. The pilot looks down at the weight after she drops it. Where is the plane located at the instant the weight hits the ground—not yet over the target, directly over the target, or past the target?

A ball is thrown horizontally from a cliff of height 90 meters with an initial speed of 45 m/s. A. How far from the base of the cliff will it strike the ground? B. What is its vertical component of
velocity when it strikes the ground? C. What is its speed when it strikes the ground?
An airplane flies horizontally at a speed of 369 km/h and drops a crate that falls to the horizontal ground below. Neglect air resistance.
A. If the altitude of the plane was 628 m, then how far, horizontally in meters, did the crate move as it fell to the ground?
B. What was the speed of the crate, in m/s, just before it hit the ground?
