Homework Statement
In a simulation of machinery at a mine site, blocks of wood were used as shown in the following experimental set-up in which the two blocks – A and B – both of mass 15 kg are joined by a string over a frictionless pulley. Block A rests on a frictionless incline of 30º. Block B is attached to the other end of the string at an angle of 40º as shown. The frictional force resisting the motion of block B is 50 N. The two blocks are then released. The site engineer has proposed the following hypothesis: “Block A will drag Block B to the left”. Confirm or refute this hypothesis
Homework Equations
I am unsure
The Attempt at a Solution
So this question popped up in a revision booklet i got. i know that block A will pull block B to the left because it has a frictionless surface and the pully is frictionless but i am unsure of how to prove this with equations :/ please help
