Payload carrying capacity decreases with the altitude achieved by the rocket.

Payload carrying capacity decreases with the altitude achieved by the rocket. Correct Answer True

The payload that can be carried to an orbit will decrease with an increase in the altitude of the orbit. Assuming the total mission energy to be constant, a smaller mass can be taken to a higher altitude. Earlier launch vehicles are upgraded to allow an increase in mission energy so that a larger mass can be carried as payload.

The formula to determine the height of the rocket above the ground at any time during the rocket's flight is given by: h = 119t - 7t2 where t = the time, in seconds, that has elapsed since the rocket was launched, and h = the height, in meters, of the rocket above the ground at time t. The value of h was 0 when the rocket hit the ground. How many seconds after the rocket was launched did it hit the ground?

A rocket is launched to travel vertically upward with a constant velocity of 20 m/s. After travelling for 35 seconds, the rocket develops a snag and its fuel supply is cut off. The rocket then travels like a free body. The height achieved by it is
Since the potential energy of an object depends on the acceleration due to gravity and since the acceleration due to gravity decreases as altitude increases, we can conclude that the potential energy of an object decreases as altitude increases.
