Two skydivers are playing catch with ball while they are falling through the air. Ignoring air resistance, in which direction would one skydiver throw the ball relative to the other if the one wants the other to catch it?
A. below the other since the ball will fall more slowly
B. above the other since the ball will fall faster
C. above the other since the ball will fall more slowly
D. directly at the other since there is no air resistance
directly at the other since there is no air resistance
