2. A 600 g spaghetti ball moving to the right at 2 m/s collides with an 800 g meatball at rest. After the collision, the 600 g ball is deflected at an angle of 37° above its original direction at a rate of 0.5 m/s. What is the magnitude and direction of the 800 g meatball's velocity?

Expert Solution
Step 1:- Concepts and formulas Used
Solution:-
1) According to the laws of conservation of Linear momentum, the linear momentum of the system remains conserved.
Along X-direction,
Px,initial = Px,final
where, Px,initial = sum of the momentum along X- direction initially(before collision)
Px,final = sum of momentum along X-direction, finally( after collision)
Similarly, Along Y-direction, we have
Py,initial = Py,final
where, Py,initial = total momentum along Y-direction before collision
Py,final = total momentum along Y-direction after collision
2) The momentum of an object moving with velocity v is given by
P = mv
here, m = mass of object
v = velocity of object
