The correct Answer is:
To find the apparent weight of a man standing in an elevator that is accelerating upwards, we can follow these steps: ### Step-by-Step Solution 1. **Identify the Given Values:** - Weight of the man (mass, \( m \)) = 80 kg - Acceleration of the elevator (\( a \)) = 6 m/s² (upward) - Acceleration due to gravity (\( g \)) = 10 m/s² 2. **Calculate the Gravitational Force:** The gravitational force acting on the man (weight) can be calculated using the formula: \[ F_g = m \cdot g \] Substituting the values: \[ F_g = 80 \, \text{kg} \times 10 \, \text{m/s}^2 = 800 \, \text{N} \] 3. **Calculate the Apparent Weight:** When the elevator accelerates upwards, the apparent weight (normal force, \( N \)) can be calculated using the formula: \[ N = m \cdot (g + a) \] Substituting the values: \[ N = 80 \, \text{kg} \times (10 \, \text{m/s}^2 + 6 \, \text{m/s}^2) = 80 \, \text{kg} \times 16 \, \text{m/s}^2 \] \[ N = 1280 \, \text{N} \] 4. **Conclusion:** The apparent weight of the man while the elevator is accelerating upwards is \( 1280 \, \text{N} \). ### Final Answer: The apparent weight of the man is \( 1280 \, \text{N} \). ---
