A rocket flies upward with a velocity of 1050 km/h and at an angle of 30 degrees to the vertical. If the rocket runs out of fuel determine:
(i) The maximum additional altitude, h.
(ii) The corresponding time.
(iii) The horizontal distance at this time
The gravitational acceleration during this flight is 9.52 m/s^2

1. a) find vertical velocity: 1050*sin30
mgh=1/2 m (1050sin30)^2 solve for h.
b) h=1050sin30*t-1/2 g t^2 solve for t.
c) distance=1050cos30*t
