A block of mass m1=3.20 kg on a frictionless plane inclined at angle 30 degrees is connected by a massless cord over a massless, frictionless pulley to a second block of mass m2 = 2.15 kg
A) draw a free body diagram for each mass.
B) Calculate the acceleration of each block
C) calculate the tension in the string
D) above a certain angle theta=theta*, the blocks will not move. Determine this angle theta.
