A block with mass m1=200 g is on a plane that makes an
angle theta = 30 degrees above the horizontal. The coefficient of
kinetic friction between m1 and the plane is "mu k"= 0.10. Mass m1
is attached by a string to another mass, m2 = 250g, which hangs
freely as shown in the picture provided. Block m2 accelerates
downward once it is set in motion. Assume pulleys is frictionles
and the weight of the string is negligible.
