thanks so much! at least now i have a idea where to start! =]

thanks so much warren! your reply increased my understanding of friction. thanks! would the acceleration of the bracket refer to the pully part? and would it have a kinetic friction instead of static friction?

hey guys! this question is a complete mind boggler to me =[ consider a bead of mass m that is free to move on a thin, circular wire of radius r. the bead is given an initial speed vo, and there is a coefficient of kinetic friction uk. the experiment is perfomred in a spaceraft drifting in...

hey guys! I've been stuck on the question for 2 days now, and it's really frustrating! I'm really hoping that someone can help me out! =] thanks in advance! a 10kg block rests on a 5kg bracket (img below). the 5kg bracket sits on a frictionless surface. The coefficents of friction between...
