A stunt team needs to construct a spectacle to keep crowds interested in their show. They have to keep the stunt people safe, as much as possible as well. The team wants a stunt man to run 9m/s across an elevated platform(8 m high) to a launching platform. The launch platform is essentially a board that sits flush with the floor and uses air pressure to accelerate it at 49m/s^2 over a distance of 175cm. The launching platform will give the stuntman enough velocity to land on a secondary, taller platform some distance away. In order to keep the jump safe for the stuntman, he must not exceed a vertical velocity of 3m/s on the descent. What must this secondary platform be in order for the stuntman to safely land? Also, what distance must this secondary platform be from the launching platform?
