A person inside an elevator counts that a simple pendulum makes 95 complete oscillations in 2.80 min. The acceleration of gravity in the building is downwards with g = 9.80 m/s2 (a) What is the period of the pendulum? (b) What is the expected length of the pendulum? (c) The person observes that the actual length of the pendulum is twice of the expected. What does it mean about the motion of the elevator? The elevator is accelerating upwards at a = g The elevator is accelerating upwards at a = g/2 Televator is accelerating downwards at a = g/2 The elevator is moving with uniform speed.The elevator is accelerating downwards at a = g (d) The same period can be obtained by a system composed of a block connected to a spring on a frictionless horizontal surface in the elevator. If the spring stiffness constant is k = 110 N/m. what must be the block's mass (in kg)?
