A block is in equilibrium on a frictionless incline plane due to a tension force from a string that is wrapped around a pulley and connected to a second hanging mass as shown in the figure. One meter of the wire weighs 0.245 N. A transverse wave on the wire has a speed of 75.0 m/s. Neglecting the weight of the wire relative to the tension in the wire, and the mass or friction of the pulley, find the masses m1 and m2 of the blocks.
