A barge with a mass 1.50 X 10^5 kg is proceeding down river at6.2 m/s in heavy fog when it collides broadside with a bargeheading directly across the river. The second barge has a mass2.78 x 10^5 kg and was moving at 4.3 m/s. Immediately afterthe impact, the second barge finds its course deflected by 18degrees in the downriver direction and its speed increased to 5.1m/s. The river current was practically zero at the time of theaccident.
a.) What are the speed and direction of motion of the firstbarge immediately after the collision?
b.) How much kinetic energy was lost in the collision?
