Q. An archer shoots an arrow with a velocity of 45.0 m/s at an angle of 50.0° with the horizontal. An assistant standing on the level ground 150 m downrange from the launch point throws an apple straight up with the least initial speed necessary to meet the path of the arrow.

(a) What is the initial speed of apple?

(b) At what time after the arrow launch must the apple be thrown so that the arrow hits the apple?
