A 2.0 kilogram mass is pulled along a horizontal table by a string attached to 0.50 kilogram mass that hangs from a string that passes over a frictionless pulley at one end of the table. The coefficient of kinetic friction between the 2.00 kilogram mass and the table is 0.125.
a) Obtain the acceleration of the 0.500 kilogram mass?
b) Obtain how long does it take for the mass, initially at rest, to fall 85.0 centimeter to the floor?
