While playing a game of billards, your 0.50kg cue ball, travelling at 1.9 m/s glances off a stationary 0.30 kg billard ball so that the billard ball moves off at 1.3 m/s at an angle of 32 degrees clockwise from the cue ball's original path. What is the final speed of the cue ball?
Two balls with masses and speed as shown collide into each other. Their plane of contact is vertical.
Determine their respective speed after the collision if the coefficient of restitution e is 0.5 and determine also
the average impulsive force that acts between them if the two balls are in contact for 0.5sec.

m= 0.5 kg
A= 3 m/s

Two astronauts on opposite ends of a spaceship are comparing lunches. one has an apple, the other has an orange. They decide to trade. Astronaut 1 tosses the .13kg apple towards astronaut 2 with a speed of 1.11 m/s. The .16kg orange is tossed from astronaut 2 to astronaut 1 with a speed of 1.21 m/s. Unfortunately the fruits collide, sending the orange off with a speed of 1.16 m/s at an angle of 42degrees. find the speed and direction of the apple, assuming an elastic collision. Please solve using conservation of momentum.
