a) An elevator travels upward at a constant speed. The elevator is hung by a single cable. Friction and air resistance are negligible.
ii) Is the tension in the cable greater than, less than, or equal to the weight of the elevator? Explain.
iii) The elevator travels downward and is slowing down. Is the tension in the cable greater than, less than, or equal to the weight of the elevator ? Explain.
ii) If moving upward i know that the tension is greater then W~ but the acceleration is 0...
then is the tension = w~? (Newton's second law state the acceleration depends on net
force )
iii) when the elevator is moving downward with slowing down, that means there consists
deceleration .. so the the tension of cable is less then the w of elevator <<< is answer
like this correct??
