A bullet is shot from a gun to demonstrate projectile motion. The initial velocity v0 of the bullet is 64 m/s and it starts at an angle of 52° above the ground. (Note that air resistance can be neglected!) Use g = 9.8 m/s2 to find:
(a) The maximum height the bullet can reach: m
(b) The flight time of the bullet: s
(c) The range of the bullet: m
