A 4600 kg helicopter accelerates upward at 2.0 m/s^2. What lift force is exerted by the air on the propellors?
I don't know how to do it.
Please help

Lift force is the upward force generated by a helicopter's rotor blades as they rotate. This force is created by the difference in air pressure between the top and bottom of the blades, resulting in a net upward force that allows the helicopter to stay in the air.
Air density plays a crucial role in lift force. As air density decreases, such as at higher altitudes, the lift force decreases as well. This is because there is less air for the rotor blades to push against, resulting in less lift force. Conversely, at lower altitudes with higher air density, the lift force will be greater.
The lift force of a helicopter can be affected by several factors, including the speed and angle of the rotor blades, the shape and size of the blades, the weight and balance of the helicopter, and environmental conditions such as air density and wind speed.
When hovering, a helicopter's lift force is equal to its weight, allowing it to stay in a stable position in the air. This is achieved by adjusting the angle of the rotor blades and the speed at which they rotate, creating an equal and opposite force to counteract the downward force of gravity.
Yes, changes in lift force can greatly impact the flight of a helicopter. Too little lift force can cause the helicopter to lose altitude or even crash, while too much lift force can make the helicopter difficult to control and potentially lead to instability or loss of control.
