1. A 9800kg rocket is travelling east along a horizontal frictionless rail at a velocity of 11m/s. The rocket is then accelerated uniformly to a velocity of 22m/s in a time of 0.75s by the expulsion of hot gases. What is the average force at which the gases are expelled by the rocket? 2. Relevant equations 3. Finding the net acceleration. 22 = 11+a(0.75) 18.333=a Finding force. F = 9800x18.33 F = 179634 What have I done wrong here?
