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?

An eagle is flying horizontally at a height of 35 meters from the ground with a velocity of 7.6m/S and with a fish in claws. It drops fish.
A) how much time passes since fish has hit the ground ?
b) what are vx and vy of the fish when it hits the ground.?
A cannonball is fired with a velocity of 40 m/s 300 above the horizontal from the top of a cliff 50 meters high. (a) How much time will it take to travel to ground level? (b) What is the highest point reached measured from ground level? (c) What is the range of the cannonball? (d) With what velocity did the cannonball strike the ground?(please help me I'm in rush, make the solution clear)
A toy rocket moving vertically upward passes by a 1.8 m -high window whose sill is 7.0 m above the ground. The rocket takes 0.16 s to travel the 1.8 m height of the window.
a) What was the launch speed of the rocket? Assume the propellant is burned very quickly at blastoff.
b) How high will the rocket go?
