two objects are connected by a light string that passes over a frictionless pulley as shown in the figure below. If M=4.0 kg and the coefficient of kinetic friction between the block and the incline is 0.35 and? = 40 degrees:
a) Find the magnitude of the acceleration of the suspended block as it falls.
b) Find the tension in the string.
c) Find the speed of each block 1.20 s after being released from rest.
