6.1 Exercise 16

Avg difficulty 2.5

A large rocket has a mass of 2.00×106kg2.00 \times 10^{6} \text{kg} at takeoff, and its engines produce a thrust of 3.50×107N.3.50 \times 10^{7} \text{N} . (a) Find its initial acceleration if it takes off vertically. (b) How long does it take to reach a velocity of 120 km/h straight up, assuming constant mass and thrust?
