Two blocks with equal masses m1 = m2
3.2 kg are connected via a pulley as shown in the above figure. Take the coefficent of kinetic friction to be
0.3 and the angle of the incline to be 40 degrees.
Find the acceleration given that
(Note: enter a negative value if the acceleration on block 1 is directed downwards.)
a) m1 is moving down
b) m1 is moving up
c) If m2 = 6.2 kg, for what values of m1 will the pair move at constant speed?
