Two astronauts comparing lunches. One has an apple and the otherhas an orange. They decide to trade. Astronaut 1 tosses the0.130 kg apple toward Astronaut 2 with a speed of 1.11m/s.the 0.160kg orange is tossed toward Astronaut 1 with a speedof 1.21 m/s. Unfortunately, the fruits collide, sending the orangeoff with a speed of 1.16 m/s at an angle of 42 degrees below theoriginal line of motion.
a) Find the final speed and direction of the apple, assumingthat it is an elastic collision.
