Two balls,projected at different times so they don't collide,have trajectories A and B,as shown below. Which statement is correct? A)v_0B must be greater than v_0A. B)Ball A is in the air for a longer time than ball B. C)Ball B is in the air for a longer time than ball A. D)Ball B has a greater acceleration than ball A. E)Ball A has a greater acceleration than ball B.

Question

Ball B has a longer horizontal distance to cover due to its initial projection angle, therefore it stays in the air for a longer period of time than Ball A. The statements in options A, B, D, and E are not necessarily true based on the given information.
