A man of 85kg is in an elevator which is accelerating upwards at the rate of 0•8m/s what is the man's apparent weight? (g=9•8m/s^2)

1 answer

To find the man's apparent weight, we need to consider the force acting on him in the elevator. The force acting on an object can be calculated using the equation:

Force = mass × acceleration

Given:
Mass of the man (m) = 85 kg
Acceleration of the elevator (a) = 0.8 m/s^2
Acceleration due to gravity (g) = 9.8 m/s^2

The force acting on the man (F) can be calculated by using the equation:

F = m × (g + a)

F = 85 kg × (9.8 m/s^2 + 0.8 m/s^2)
F = 85 kg × (10.6 m/s^2)
F = 901 kg·m/s^2

Thus, the man's apparent weight is approximately 901 kg·m/s^2.
