A simultaneous apparatus is attached to a ring stand and demonstrated how two objects shot in different directions can hit the ground at the same time. One object is dropped while the other object is given an initial velocity in the x-direction. Due to the acceleration of gravity being the only acceleration of each object, they fall to the ground at the same rate. The second object having a velocity in the x-direction will only change the position relative to the ring stand, but it will not change the time it takes for the two objects to hit the ground.

What is the difference in time if the second object is fired with an initial velocity at exactly 1 degree above the horizontal? Would it matter if the objects had different masses?
