1. The problem statement, all variables and given/known data A block of mass m = 0.500 kg rests on top of a block of mass M = 2.50 kg which is on the floor. A string attached to the block of mass M is pulled so that its tension is T = 7.00 N at a 25.0o angle to the horizontal as shown. The blocks move together across the horizontal surface. The coefficient of static friction at the surface between the blocks is μs = 0.410. There is no friction at the surface between block M and the floor. a) What is the acceleration of the two-block system? b) What is magnitude and direction of the total force (combination of normal force and frictional force) on block m due to block M? c) The tension T is now increased - what is the maximum tension, Tmax, with which the string can be pulled such that the blocks continue to move together (i.e. that the block of mass m does not start to slide on top of the block of mass M)? 2. Relevant equations 3. The attempt at a solution I solved part a and got 2.11 m/s^2 but i have no clue about part b and c. please help me.
