2. A soccer ball is kicked into the air so that the path of its flight can be modeled by the function, wheret is in seconds and x is meters above ground: x(t) = -4.9t2 +9.8t + 5 %3D a) At what time will the ball land? b) How many meters above ground was the ball kicked? c) What is the maximum height the ball will reach and at what time will this occur? d) What is the acceleration (with direction) of the ball at t=3 s?
