Two blocks are connected over a massless, frictionless pulleys. The mass of block 1 , m1 =10.0kg and mass of block 2 ( m1  =15kg). The coefficient of friction between block 2 and the surface is 0.25

The angle of the incline is 30◦ . 

a) show all the force vectors acting on the two blocks. 

b) Find the acceleration of the two block if block 2 moves upward on incline (10 points)

Hint: both blocks have the same acceleration because they are connected to each other by the string.
