An airplane is to drop an abject to hit a target on the ground. The plane is flying at a constant speed of 300 km/h horizontally, and it is at an altitude of 300 m above the ground.
a. How far in advance should the object be let go in order for it to reach the target?
b. If, by mistake, the pilot missed the point that you found in Part a, and flew another 100 m straight ahead, with what initial speed should he force down the object so it can still hit the target?
