A rocket is launched at an angle of 56.0° above the horizontal with an initial speed of 103 m/s. It moves for 3.00 s along its initial line of motion with an acceleration of 31.0 m/s2. At this time its engines fail and the rocket proceeds to move as a free body.
(a) Find the maximum altitude reached by the rocket.
(b) Find its total time of flight.
(c) Find its horizontal range.
On an extra note. I've done a lot of the practice problems and gotten those wrong... I don't know why I keep getting this wrong... But my answers for part a have been fairly close it seems like I keep getting my y-speed when the engine fails wrong by about 2.something and I don't know why but so far time has been around 36-37 seconds
