Asked by Lee
On takeoff, the combined action of the engines and the wings of an airplane exert a force of 8.00 x 103 N on the plane upward at an angle of 65.0˚ above the horizontal. The plane rises with constant velocity in the vertical direction while continuing to accelerate in the horizontal direction.
a) What is the weight of the plane? b) What is the horizontal acceleration of the plane?

a) weight; has to equal force up (less air friction) 8E3*sin65
b) ignoring air friction,
f=ma
8E3*cos65=massplane*a
solve for a
b) ignoring air friction,
f=ma
8E3*cos65=massplane*a
solve for a
