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)?

Explanation:

Mass of Apple,

Mass of orange,

Initial speed of orange,

Initial speed of Apple,

Final speed of the orange,

(a) Let is the final sped of the apple. It can be calculated using the law of conservation of momentum as :

So, the final speed of the apple is 1.32 m/s

(b) The direction of the apple in this case is given by:

Hence, this is the required solution.
