A rocket burns 0.01kg of fuel each second and ejects it as a gas with a velocity of 5,000m/s. What force does the gas exert on the rocket?
A
500,000N
B
500N
C
50N
D
5,000N
E
50,000N
Verified Correct Answer: C.
Physical Principles & Numerical Solution
F =\(\frac{m(v - u)}{T}\)
= \(\frac{0.01(5000 - 0)}{1}\)
= 50N
