A rocket is launched at an angle of 56.0° above the horizontal with an initial speed of 99 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 30.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile.
a) Find the maximum altitude reached by the rocket.
b) Find its total time of flight.
C) Find its horizontal range.
