A 9800 kg rocket is travelling east along a horizontal fricitonless rail at a velocity of 11 m/s. The rocket is then accelerated uniformly to avelocity of 22 m/s in a time of 0.75 s by the expulsion of hot gases. What is the average force with which the gases are expelled by the rocket?

F = m x a
Plug in the values, find acceleration and plug that in for a.
F = 9800 * a
Solve for F.
