A projectile is fired with an initial speed of 21 m/s at an angle of 60* above the horizontal. The object hits the ground 13 s later. (A) how much higher or lower is the launch point relative to the point where the projectile hits the ground. (B) To what maximum height above the launch point does the projectile rise? (C) What is the magnitude and direction of the projectile's velocity at the instant it hits the ground?
