Helicopter with weight W is ascending with zero acceleration. Upward force F on the helicopter is:
Correct answer: D. F=W
- A. F>W
- B. F<W
- C. F=0
- D. F=W
Explanation
When a helicopter is ascending with zero acceleration, the upward force on the helicopter is equal to its weight. So, the upward force (F) exerted on the helicopter is indeed equal to its weight (W). It's all about achieving that balance of forces to maintain a steady ascent.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
