A rocket fired vertically up from the north pole achieves a velocity of29000 km/h at an altitude of356km when its fuel is exhausted. Calculate the additional vertical heighthreached by the rocket before it starts its descent back to the earth. The coasting phase of its flight occurs above the atmosphere. Consult Fig. 1/1 in choosing the appropriate value of gravitational acceleration and use the mean radius of the earth from Table D/2. (Note: Launching from the earth's pole avoids considering the effect of the earth's rotation.)

Answer:h=__________km
