6 Two projectiles, X and Y, are fired into the air from the same place on level ground and reach thesame maximum height, as shown.path of Xgroundpath of YProjectile X is fired vertically upwards and projectile Y is fired at an angle to the horizontal.Air resistance is negligible.Which statement is correct?A X and Y are at rest at their maximum heights.B X and Y are fired with the same speed.C X and Y take the same time to return to the ground.D X and Y travel the same distance.

If two projectiles are launched with the same initial speed but at different angles, which one will stay in the air for a longer time?*1 pointA . The one launched at a lower angleB . The one launched at a higher angleC. Both will stay in the air for the same timeD . It depends on the initial speed
