A ball is projected from ground level at an initial angle of 33.1 degrees above the horizontal. After 0.74 seconds, the ball hits a wall that is 28.4 meters away. At what height above the ground does
the ball hit the wall?

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
