Solve the all parts of given question:
Question: A basketball player wants to know how fast the ball must be traveling when it leaves his hands to make it into the basket. The player is standing 15 m from the basket, and releases the ball at a height of 2.1 m from the ground. The basket is 3.05 m high. In order for the ball to make it into the basket, it must reach a minimum height of 4.2 m.
Part A: At what angle is the player going to throw the ball to use the least amount of effort?
Part B: What is the minimum velocity with which the ball must be thrown to make the basket?
Part C: How long is the ball in the air?
Part D: If the basketball has a mass of 625 g, and accelerates over a distance of 0.21 m before the player releases it, what force does the player exert on the ball?
I need help to determine the minimum velocity with which the ball must be thrown to make the basket.
