16-18 An elevator car is suspended by a single steel cable. The carhas a mass of 520 kg and it contains a passenger whose mass is 80kg. The mass of the cable can be ignored. 16. If the elevator istraveling vertically downwards at a constant speed of 2.00 m/s,calculate the tension in the cable.
17. If the elevator is accelerating downwards with a constantacceleration of magnitude 1.00 m/s2, calculate the tension in thecable.
18. If the maximum tension that the cable can safely withstand is9000 (N), and the maximum upward
acceleration of the elevator is 1.00 m/s2, how many 80 kgpassengers may be safely carried in the elevator?
