A fully loaded Saturn V rocket has a mass of 2.92 x 106
kg. Its engines have a
thrust of 3.34 x 107 N.
a. What is the downward force of gravity on the rocket at blastoff?
b. What is the unbalanced force on the rocket at blastoff?
c. What is the acceleration of the rocket as it leaves the launching pad?
d. As the rocket travels upwards, the engine thrust remains constant, but the
mass of the rocket decreases. Why?
e. Does the acceleration of the rocket increase, decrease, or remain the
same as the engines continue to fire?
