Problem: One end of a 14.0 m long rubber tube with total mass 0.800kg is fastened to a fixed support. A cord attached to the other end passes over a pulley and supports an object with mass of 7.50kg. The tube is struck a transverse blow at one end.
Part A: Find the time required for the pulse to reach the other end.
I need help to determine the time required for the pulse to reach the other end.
