Best ResponseYou've already chosen the best response.1A 60 Kg person gets on an elevaator in the Mclennan Physics labs at the university of Toronto. Naturally, there's a scale (measuring Newtons) on the floor, The person steps on the scale and presses "UP". The scale reads 700N (UP). Determine the acceleration of the elevator. Draw a free body diagram.

Best ResponseYou've already chosen the best response.1dw:1442528711236:dw here's the thing, when the elevator is going up, the acceleration of elevator = acceleration of student

Best ResponseYou've already chosen the best response.1could you please deinfe Tension for me please!!!

Astrophysics

Best ResponseYou've already chosen the best response.1Tension is the applied force here, which be exerted by pushing or pulling the object, but since the elevator is going up, it is being pulled so that is the applied force here (Tension) which is opposing weight

Best ResponseYou've already chosen the best response.1Oh ok cuz i know it by F sub applied, i didn't know it's tension too..

Best ResponseYou've already chosen the best response.1Applied force = tension, it doesn't matter :P, people often confuse it
