A golf ball is thrown straight up in the air at a velocity of 8.4 m/s. Assume an acceleration due to gravity of 9.81 m/s^2.                                                                           

a) Determine the maximum height the golf ball reaches.

b) How long will it take the golf ball to reach its maximum height?

c) How long will it take the golf ball to fall from its maximum height to the height from which is was initially launched?
