Question

Please solve for:

-Magnitude of acceleration of the rocket in m/s^2
-Direction of acceleration of the rocket relative to the ground in degrees

The rocket moves in a vertical plane and is being propelled by a thrust T of 32 kN. It is also subjected to an atmospheric resistance R of 9.6 kN. If the rocket has a velocity of 3 km∕s and if the gravitational acceleration is 6 m∕s^2 at the altitude of the rocket calculate:

-Magnitude of acceleration of the rocket in m/s^2
-Direction of acceleration of the rocket relative to the ground in degrees

given 

v (time-rate-of-change of the magnitude of velocity of rocket) = 6 m/s^2
p (radius of curvature of rockets path)= 3000 km

m (mass of rocket at instant considered) = 2000kg
