A 60kg block slides along the top of a 100kg block with an acceleration of 2.0m/s^2 when a horizontal force of 350N is applied. The 100kg block sits on a horizontal frictionless surface, but there is friction between the two blocks.
(a) Find the coefficient of kinetic friction between the blocks.
(b) Find the acceleration of the 100kg block during the time that the 60kg block stays in contact.
