Question

At 363 ft tall, the Saturn V rocket was the largest rocket ever sent into space. Stage 1 of the rocket, built by Boeing,

Answer 1

Answer:

  f'(t) = -15 tons/second

Step-by-step explanation:

Using the power rule, the derivative of f(t) is ...

  f'(t) = -15 . . . tons/second

f(t) is the fuel weight, so f'(t) is the rate at which fuel weight is changing. The rocket is using fuel at the rate of 15 tons per second.

_____

Comment on units

The units of the equation for f(t) are ...

  f(t) = 2520 tons - (15 tons/second)(t seconds)

The derivative is the coefficient of (t seconds), so is (-15 tons/second).
