Question

A satellite with a mass of 120 kg fires its rocket thrusters, which give an impulse of 7440 kg-m/s. What was the total change in the velocity of the satellite — that is, what was the total AV?
A. 17 m/s
B. 88 m/s
C. 45 m/s
D. 62 m/s

Answer 1

From the calculation and the momentum of the body, the velocity is 62 m/s

What is momentum?

The term momentum refers to the product of mass and velocity. Now recall that the rate of change of momentum is equal to the impressed force.

Hence;

7440 kg-m/s = 120 kg * v

v= 7440 kg-m/s/120 kg

v =  62 m/s
