The pilot weighting 686N dived down with an acceleration of 9.8m sec-2 its apparent weight is
Correct answer: D. Zero
- A. 343N
- B. 1372 N
- C. 686 N
- D. Zero
Explanation
The net force is equal to the sum of the gravitational force and the force due to acceleration:Net force = Gravitational force + Force due to accelerationNet force = 686N + (mass × acceleration)Since the gravitational force is equal to the weight, we have:Net force = Weight + (mass × acceleration)Net force = 686N + (mass × 9.8 m/s²)Now, if the pilot is in free fall with no other external forces acting on them, we can consider the net force to be zero because the gravitational force and the force due to acceleration cancel each other out. Therefore, the apparent weight of the pilot in this scenario is zero.
