Compute each part of given question:
Question: 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 250 m above the ground.
Part I: How far in advance should the object be let go in order for it to reach the target?
Part II: If, by mistake, the pilot missed the point that you found in Part a, and flew another 60.0 m straight ahead, with what initial speed should he force down the object so it can still hit the target?
Please explain how you came to your conclusion.
