1 two connected masses m = 400g and m2 = 550g are such that my moves down an inclined
plane and m, moves along a horizontal surface. the string is light and inextensible and the
coefficient of kinetic friction between m, and the inclined plane is 0.35 while the coefficient
of kinetic friction between m, and the horizontal surface is he when 8 = 45° the masses
move at a constant speed.
a) determine hk
b) calculate the acceleration ife is raised to 50°.
