A body of mass 3.5 kg makes an elastic collision with another body at rest and continues to move in the original direction but with 1/4 of its original speed. (a) What is the mass of the other body? (b) What is the speed of the two-body center of mass if the initial speed of the 3.5 kg body was 6.9 m/s?
