Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

You're playing a cartoony racing video game, with a character on a motorcycle. You drive your character off a ledge at 15 m/s. The next ledge for the character's bike to land on is 25 m away (horizontally) and 12 m below. Assume the video game has realistic physics coded into it, except that acceleration due to gravity is only 8.0 m/s^2. a) will your character land on the next platform? b) whether they land or not, find their velocity (magnitude and direction) as they either land on or pass through the 12 m below position.
