Question
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?Select one:a.4.06 × 107 Nb.1.47 × 108 Nc.3.77 × 107 Nd.7.54 × 107 N
Solution
The total upward force (thrust) provided by the engines can be calculated using the formula for thrust:
Thrust = mass flow rate * exhaust velocity
Given in the problem, the mass flow rate is 14,000 kg/s and the exhaust velocity is 2900 m/s.
Substituting these values into the formula gives:
Thrust = 14,000 kg/s * 2900 m/s = 4.06 × 10^7 N
So, the correct answer is a. 4.06 × 10^7 N.
