An airplane with a speed of 79.8 m/s is climbing upward at an angle of 43.1 ° with respect to the horizontal. When the plane's altitude is 920 m, the pilot releases a package. (a) Calculate the distance along the ground, measured from a point directly beneath the point of release, to where the package hits the earth. (b) Relative to the ground, determine the angle of the velocity vector of the package just before impact.
A person is standing on top of a building. While standing at the edge of the building the person throws a water balloon downward with a speed of 14 m/s and at an angle of 44° below the horizontal. It takes 2.9 s for the water balloon to hit the person's friend. (a) How high is the building in meters? (b) How fast is the water balloon moving when it hits the friend on the ground? Give your answer in m/s. (c) What was the horizontal distance between the friend on the ground and the building in meters?

Aaron Rodgers throws a football at 20.0 m/s to his wide receiver, who is running straight down the field at 9.4 m/s. If Aaron throws the football when the wide receiver is 10.0 m in front of him, (a) at what angle does Aaron have to launch the ball so the ball will be at the same height as the receiver when the receiver makes it to 20.0 m in front of Aaron? (b) Will the receiver be able to catch the ball?
A rock was thrown horizontally from a 100.0 m high cliff. It strikes the ground 90.0 m from the base of the cliff. a) At what speed was it thrown? b) How long did it take to hit the ground. c) Neglecting wind resistance, which component of velocity is affected by gravity VERTICAL or HORIZONTAL? d) Sketch the trajectory of the rock as it falls to the ground and include the velocity vector at the beginning, midway down, and just before striking the ground. e) After you determine the total time in the air, you can then determine the final vertical velocity vector combined with the horizontal velocity determined earlier. Use these vectors to determine the resultant velocity vector just before landing. Recall using Pythagorean theorem to find the magnitude of the velocity vector and trigonometry for the angle below the horizontal that the resultant vector strikes at.
