Billy and Joe are doing science experiments in the skating rink at SM Mall of Asia. Billy of mass equal to 80kg was pushed and slid due east, and Joe with mass equal to 50kg was pushed towards north; colliding with each other. After the collision, Billy is observed to move 37° N of E with a speed of 6 m/s. Also, Joe is observed to move at S 67° E with a speed of 9 m/s. If the rink is assumed to be frictionless, By how much did the total kinetic energy of the two people decrease after the collision?
