The helicopter in the drawing is moving horizontally to the right at a constant velocity. the weight of the helicopter is w=50900 n. the lift force l generated by the rotating blade makes an angle of 21.0° with respect to the vertical.
(a) what is the magnitude of the lift force?
(b) determine the magnitude of the air resistance r that opposes the motion.

Atriangle with equal sides of length 10 cm has -2.5-nc charged objects at each corner. part a determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. determine the direction of the electrical force exerted on the object at the top corner due to the two objects at the horizontal base of the triangle. horizontally rightward vertically downward vertically upward horizontally leftward
