A 4.0 kg block of wood sits on a table. A string is tied to the wood,
running over a pulley and down to a hanging object. The greatest mass that can be
hung from the string without moving the block of wood is 1.8 kg. Calculate the coefficient
of static friction between the block of wood and the table.
4.0 kg and 1.8 kg- mass
The Attempt at a Solution
so i assume the block isnt moving so fnet would be 0, fn=fg so 4.0(9.8) ---> 39.2
i dont have fs and mew so how am i supposed to solve this?
