The arrangement in the drawing
shows a block (mass = 16.0 kg) that is held in position on a
frictionless incline by a cord (length = 0.53 m). The mass per unit
length of the cord is 1.26 × 10 − 2 kg/m, so the mass of the cord
is negligible compared to the mass of the block. The cord is being
vibrated at a frequency of 90.5 Hz (vibration source not shown in
the drawing). What is the largest angle θ at which a standing wave
exists on the cord?

Block A in the figure has mass mA = 4.20 kg, and block B has mass mB = 2.40 kg. The coefficient of kinetic friction between block B and the horizontal plane is μk = 0.520. The inclined plane is frictionless and at angle θ = 34.0°. The pulley serves only to change the direction of the cord connecting the blocks. The cord has negligible mass. Find (a) the tension in the cord and (b) the magnitude of the acceleration...
