Two blocks are connected by a wire that has a mass per unit length of 25.9 x 10-4 kg/m. One block has a mass of 25.9 kg, while the other has a mass of 45.9 kg. These blocks are being pulled across a horizontal frictionless floor by a horizontal force P that is applied to the less massive block. A transverse wave travels on the wire between the blocks with a speed of 451 m/s (relative to the wire). The mass of the wire is negligible compared to the mass of the blocks. Find the magnitude of P.
