Two astronauts on opposite ends of a spaceship are comparing lunches. one has an apple, the other has an orange. they decide to trade. atronaut 1 tosses the 0.125 kg apple toward astronaut 2 with a speed of vi1=1.13 m/s. the 0.160 kg orange is tossed from astronaut 2 to astronaut 1 with a speed of 1.18 m/s. unfortunately, the fruits collide, sending the orange off with a speed of 0.999 m/s in the negative y direction.

a) what are the final speed of the apple in this case (vf1)?

b) what are the direction of the apple in this case (theta)?
