A rocket is launched at an angle of 56.0° above the horizontal with an initial speed of 101 m/s. The rocket moves for 3.00 s along its initial line of motion with an acceleration of 29.0 m/s2. At this time, its engines fail and the rocket proceeds to move as a projectile.
What is the highest altitude reached by the rocket?
Total time of flight?
break it into two parts, solve each independently, the acceleration part, the free fall part. Then add the distances.posted by bobpursley
