Two blocks of masses m1=2kg and m2=5kg hang over a massless pulley as in the figure. A force F=100N acting on the axis of the pulley accelerates the system upward. Find : a) the acceleration of each block b) the tension in the string.

Best ResponseYou've already chosen the best response.0How would this problem be done with the force acting on the axis? that is new to me

Best ResponseYou've already chosen the best response.0@3psilon it just means the system is pulled by a force upwards, i guess.

Best ResponseYou've already chosen the best response.0So usually in an Atwell problem like this the acceleration is the same right? But I guess that force changes the acceleration of both?

Best ResponseYou've already chosen the best response.0yes.. acceleration of both the blocks without the force is 30/7 m/s2 .. if that could help..

Best ResponseYou've already chosen the best response.1Actually, this problem is simpler than an Atwood machine. Since the pulley is massless, it is very easy to find the tension in the string, and the accelerations of M1 and M2.
