A 46.7-kg person, initially at rest, throws a 0.143-kg snowball forward with a horizontal speed of 33.5 m/s. A second person, with a mass of 47.5 kg, catches the snowball. Both people are on skates. The first person is initially at rest, as mentioned, and the second person is initially moving with a speed of 1.45 m/s toward the first person. Disregard air resistance and the friction between the skates and the ice. Take the direction in which the snowball is thrown to be the positive direction. Indicate the directions of the final velocities with the signs of your answers. To receive full marks, you must include a diagram showing the physical situation. (a) Calculate the velocity of the first person immediately after they throw the snowball. (b) Calculate the velocity of the second person immediately after they catch the snowball. (a) thrower (first person)     m/s (Give your answer to at least three decimal places.)(b) catcher (second person)     m/s (Give your answer to at least three decimal places.)
