Homework Statement
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.
Homework 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
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.
