Answer:
Force the floor exerts on the passenger is 833 N.
Explanation:
- Weight of passenger (
) = mg = 85 × 9.8 N = 833 N
- Force the floor exerts on the passenger (
) = ?
- For the elevator with the speed as 2.0 m/s the net force is zero, it means that the force is balanced.
i.e. = - = -mg = 833 N
hence is 833 N
- If the lift was not at a constant speed i.e. if it had acceleration (
) then the case would be different.
