Question

Consider a pulley-block system to be attached to an elevator ceiling. The elevator begins to accelerate upwards from its rest configuration with a constant acceleration of a L = 2 m/s 2. At this instant, the 60 kg block A is released from rest. If the masses of the pulleys and the cord arc neglected, determine the speed of the 30 kg block B in 3 seconds. (Be advised Newton's II law is used in inertial frame of reference i.e. in F = ma, a is the acceleration of the particle as observed by an inertial observer). Also determine the tension in each cable (i.e. the one attached to B, and the other attached to A)

Explanation / Answer

Hi again,

I have read your comment and I really understand your concern. Although answer seems to be easy, when you try to solve it by yourself without seeing the solution, you will see that it is not that much easy. There are lots of possibilities that you need to take into consideration while solving the question. Although I was sure about my answer, I have reviewed the topic from two different sources just to assure you.
