A 150N block rests on a table. The suspended mass has a weight of 73N.
a) What is the magnitude of the minimum force of static friction required to hold both blocks at rest? Answer in units of N
b)What minimum coeﬃcient of static friction is required to ensure that both blocks remain at rest?
Can someone please explain the answer when they give it?
I am guessing these blocks are connected over a frictionless pulley.
hanging force=73 N.
that is pulling on the large block
b. 73=mu*mg solve for m u
What would you use for the m when you multiply it by 9.81?
