A circus performer throws an apple toward a hoop held by a performer on a platform (Fig. P4.27). The thrower aims for the hoop and throws with a speed of 24 m/s. At the exact moment the thrower releases the apple, the other performer drops the hoop. The hoop falls straight down. 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? Figure P4.27
