Two friends, John and Kathy, are rollerblading. John has a mass of 70.0 kg and rollerblades at a speed of 8.50 m/s behind Kathy whose mass is 55.0 kg and speed is 5.00 m/s. John accidentally bumped into Kathy and grabbed her around the waist and they maintain their balance. What is their velocity after John grabbed Kathy around the waist?
