A circus performer throws an apple toward a hoop held by a performer on a platform (see figure below). The thrower aims for the hoop and throws with a speed of 30 m/s. At the exact moment the thrower releases the apple, the other performer drops the hoop. The hoop falls straight down. (Assume d = 21 m and h = 43 m. Neglect the height at which the apple is thrown.)

(a) At what height above the ground does the apple go through the hoop?

(b) If the performer on the platform did not drop the hoop, would the apple pass through it? Yes or No
