Question

A special rocket can produce 7.66 ✕ 10^5 N of instantaneous thrust with an exhaust speed of 3.05 ✕ 103 m/s in vacuum. What mass of fuel does the engine burn each second to produce this thrust? (Enter your answer in kg/s.)

Answer 1

The mass of fuel the engine burn each second to produce a thrust of 7.66×10⁵ N is 2.5×10² kg/s.

What is mass?

Mass can be defined as the quantity of matter contained in a body. The S.I unit of mass is kilogram(kg)

To calculate the mass the engine burns each seconds, we use the formula below.

Formual:

• M = T/v............. Equation

Where:

• M = Mass per seconds of the rocket
• T = Thrust
• v = Velocity

From the question,

Given:

• T = 7.66×10⁵ N
• v = 3.05×10³ m/s

Substitute these values into equation 1

• M = (7.66×10⁵)/(3.05×10³)
• M = 2.5×10² kg/s

Hence, the mass of fuel burned in each second is 2.5×10² kg/s.
