The propellers of a small airplane produce a forward thrust of 6.2 x 104 N on the plane which has a mass of 2.8 x 104 kg. The plane is in level flight. a. Draw a labeled force diagram for the airplane using congruency marks to denote forces that are equal in magnitude. b. Write a net force equation for the axis along which the forces are not balanced. c. Calculate the plane's acceleration.
