A blue rubber ball (78.2 kg) traveling east with a speed of 6.6 m/s comes into contact with a red rubber ball traveling west at a speed of -8.7 m/s. As they bounce off, the blue ball bounces back with a speed of -2 m/s and the blue ball bounces backwards with a speed of 7.8 m/s. Using momentum, what is the mass of the red rubber ball? Round to 1 decimal.
