A rocket fired vertically up from the north pole achieves a velocity of 25 000 km/h at an altitude of 339 km when its fuel is exhausted. Calculate the additional vertical height h reached 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= i km

Question
A rocket fired vertically up from the north pole achieves a velocity of 25 000 km/h at an altitude of 339 km when its fuel is exhausted.
Calculate the additional vertical height h reached 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= i
km
