At one instant of time a rocket is traveling in outer space at 2500 m/s and is exhausting fuel at a rate of 100 kg/s. If the speed of the fuel as it leaves the rocket is 1500 m/s, relative to the rocket, the thrust is: A) 0 B) 1.0 * 10⁵ N C) 1.5 * 10⁵ N D) 2.9 * 10⁵ N E) 2.5* 10⁵ N

Question

Quizplus · Accepted Answer

The thrust is calculated using the formula: Thrust = (mass flow rate) * (exhaust velocity). Here, the mass flow rate is 100 kg/s and the exhaust velocity is 1500 m/s. Therefore, Thrust = 100 kg/s * 1500 m/s = 1.5 x 10^5 N.
