For an optimal rocket, the specific impulse and structural ratio can have any values.

For an optimal rocket, the specific impulse and structural ratio can have any values. Correct Answer False

In case of optimal rockets, there is a unique set of structural ratio and specific impulse for each stage. Unless these specifications met, the total payload ratio is not maximum.

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?
