A person who weight 800 N steps ontoa scale that is on the floor of an elevator car. If the elevator acelerates upward at a rate of `5 m//s^(2)`, what will the scale read ?

A body hangs from a spring balance supported from the roof of an elevator. (a) If the elevator has an upward acceleration of 2.45 ms^(-2) and the balance reads 50N, what is the true weight of the body? (b) Under what circumstances will the balance read 30N? (c) What will be the balance reading if the elevator, cable breaks?

A simple pendulum of length 1m is attached to the ceiling of an elevator which is accelerating upward at the rate of 1m//s^(2) . Its frequency is approximately :-

A 2kg block hangs without vibrating at the bottom end of a spring with a force constant of 400 N//m . The top end of the spring is attached to the ceiling of an elevator car. The car is rising with an upward acceleration of 5 m//s^(2) when the acceleration suddenly ceases at time t = 0 and the car moves upward with constant speed (g = 10 m//s^(2)) What is the angular frequencyof the block after the acceleration ceases ?

Passage X) A 2kg block hangs without vibrating at the bottom end of a spring with a force constant of 400 N/m. The top end of the spring is attached to the ceiling of an elevator car. The car is rising with an upward acceleration of 5m/ s^(2) when the accleration suddenly ceases at t=0 and the car moves upward with constant speed. (g=10m/ s^(2) ) What is the angular frequency of oscillation of the block after the acceleration ceases?

Passage X) A 2kg block hangs without vibrating at the bottom end of a spring with a force constant of 400 N/m. The top end of the spring is attached to the ceiling of an elevator car. The car is rising with an upward acceleration of 5m/ s^(2) when the accleration suddenly ceases at t=0 and the car moves upward with constant speed. (g=10m/ s^(2) ) The initial phase angle observed by a rider in the elevator, taking upward directioin to be positive and positive extreme position to have pi/2 phase constant, is equal to

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?
