1. The problem statement, all variables and given/known data An Airbus A320 jetliner has a takeoff mass of 75,000 kg. It reaches its takeoff speed of 82 m/s in 35s. Find the Thrust of the engines, don't worry about air resistance, but rolling friction is substantial. 2. Relevant equations Fnet=mass*acceleration a=(82/35) mass=75000 rolling_friction=mu*n (n=normal force) (mu=friction coefficient) Fnetx=rolling_friction-thrust Fnety=n-weight(m*g (gravity)) n=mg 3. The attempt at a solution I got as far as: Thrust=mu(m*g)-m*a I know that I need to solve for mu, but I can't seem to find a good way to further relate the equations.
