Projectile A is launched with a horizontal velocity of 20 m/s from the position shown in the figure. 20 m/s h 5 m B g=9.8 m/s² 0.25 s later B is launched from the position shown, with a launch angle of =22° to the horizontal. The launch position of B is h =21.2 m below the position from where A was launched, and 5 m to the right of it. Assume both projectiles have a downward acceleration of 9.8 m/s². Assume the projectiles are small compared to the scale of their motion. Hint: A is directly above B at the moment B is launched. What speed must B be launched with in order for it to have a mid-air impact with A? 21.57 m/s How long after the launch of B does the impact occur? 2.24 sec How far from the launch position of A does the impact occur? Number m
