The helicopter in the drawing is moving horizontally to the right at a constant velocity. The weight of the helicopter is W = 55,500 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.

mmh The helicopter in the drawing is moving horizontally to the right at a constant velocity $\vec{v}$ . The weight of the helicopter is $W=53800 \mathrm{N}$ . The lift force $\vec{L}$ generated by the rotating blade makes an angle of $21.0^{\circ}$ with respect to the vertical. (a) What is the magnitude of the lift force? (b) Determine the magnitude of the air resistance $\vec{R}$ that opposes the motion.

A helicopter of mass $1000 \mathrm{~kg}$ rises with a vertical acceleration of $15 \mathrm{~m} \mathrm{~s}^{2}$. The crew and the passengers weigh $300 \mathrm{~kg}$. Give the magnitude and direction of the (a) force on the floor by the crew and passengers, (b) action of the rotor of the helicopter on the surrounding air. (c) force on the helicopter due to the surrounding air.
