A 1.33kg block is sitting on a table. The block and table have a coefficient of static friction between themselves of 0.85; and a coefficient of kinetic friction of 0.59. A string is tied to the block and passes over a frictionless and massless pulley. A mass is then hung from the string.
a) How much mass can hang from the string before the block begins to slide?
b) If 20% extra mass is hung from the string, what would be the acceleration of the block?
