A block of mass 3.1 kilogram rests on a frictionless inclined plane, held in place by a string of mass 0.023 kilogram. The angle of the plane from the horizontal is 32 degree, and the string length is 1.5 meter. Determine how long does it take a wave to travel from one end of the string to the other? Note: Since the string is so much less massive than the block, the mass of the string can be neglected when computing its tension.
