What normal force does the floor of an elevator exert on a 90 kg person if the person / elevator system accelerates upward at `1 m//s^(2)` ?

A 75 kg man stands in a lift. What force does the floor does the floor exert on him when the elevator starts moving upwards with an acceleration of 2.0ms^(-2) . ? Take g = 10 ms^(-2) .

You are designing an elevator for a hospital. The force exerted on a passenger by the floor of the elevator is not to exceed 1.60 times the passenger's weight. The elevator accelerates upwards with constant acceleration for a distance of 3.0 m and then starts to slow down. What is the maximum speed (in ms^(-1) ) of the elevator?

The upwards normal force exerted by the force of an elevator on a passenger who weighs 600 N is 570 N. The acceleration of passanger is

A barometer kept in an elevator accelerating upwards reads 76 cm of Hg. If the elevator is accelerating upwards at 4.9 "ms"^(-2) , what will be the air pressure in the elevator?

The force exerted by the floor of an elevator on the foot of a person standing there is more than the weight of the person if the elevator is :

A spring mass system is hanging from the ceiling of an elevator in equilibrium. The elevator suddenly starts accelerating upwards with acceleration a, consider all the options in the reference frame of elevator.

A spring mass system is hanging from the celling of an elevator in equilibrium. The elevator suddenly starts accelerating upwards with acceleration a. Find (a) the frequency and (b) the amplitude of the resulting SHM.

A 71 kg man stands on a bathroom scale in an elevator. What does the scale read if the elevator is ascending with an acceleration of 3.0" m"//"s"^(2) ?

A 900 kg elevator hangs by a steel cable for which the allowable stress is 1.15xx10^(8)" N/m"^(2) . What is the minimum diameter required if the elevator accelerates upward at 1.5" m/s"^(2)?" Take "g=10" m/s"^(2) .
