At liftoff,the engines of the Saturn V rocket consumed 14,000 kg/s of fuel and exhausted the combustion products at 2900 m/s.What was the total upward force (thrust)provided by the engines? A) 3.77 × 10⁷ N B) 7.54 × 10⁷ N C) 1.47 × 10⁸ N D) 4.06 × 10⁷ N

Question

Quizplus · Accepted Answer

The upward force (thrust) provided by the engines can be calculated using the formula:

Thrust = mass flow rate * exhaust velocity

where mass flow rate is the amount of fuel consumed per unit time and exhaust velocity is the velocity at which the combustion products are expelled.

In this case, mass flow rate = 14,000 kg/s and exhaust velocity = 2900 m/s. Therefore,

Thrust = 14,000 kg/s * 2900 m/s = 4.06 × 10^7 N

So the correct answer is D.

At Liftoff,the Engines of the Saturn V Rocket Consumed 14,000
