In a rocket, fuel burns at the rate of 1kg/s. This fuel is Ejected from the rocket with a velocity of 60km/s. What force will be exerted on the rocket?

Answer 1

F = m * a
1 N = 1 kg * 1 m / s^2
M = 1 kg / sec
V = 60 km /sec
F = 1 kg / sec * 60 km / sec
F = 60 * 1000 * kg / sec^2
F = 60000 N
Ans: 60,000 N
