Two astronauts on opposite ends of a space ship are comparing lunches. One has an apple, the other has an orange. They decide to trade. Astronaut 1 tosses the 0.160 kg apple toward astronaut 2 with a speed of 2.15 m/s. The 0.130 kg orange is tossed from astronaut 2 to astronaut 1 with a speed of 1.05 m/s. Suppose that after the collision the orange moves exactly in the negative y direction with a speed of 1.52 m/s. What is the final speed and direction of the apple in this case?
