Two identical objects start at the same height above level ground. Simultaneously, object A is launched at an angle of 30° above horizontal and object B is launched at angle of 30° below horizontal.

Two identical objects start at the same height above level ground. Simultaneously, object A is launched at an angle of 30° above the horizontal and object B is launched at an angle of 30° below the horizontal. Both objects have a launch speed of 20 m/s. Assume that air resistance is negligible.


a) Which object hits the ground first, or do they hit the ground at the same time?


b) Which object hits the ground with the greatest speed, or do they hit the ground with the same speed?


c) If the two objects started at a height of 5.0 m above the ground, how far apart would they land?
