If Car A, with mass m, is moving north with a speed v, collides, Car B, with mass 2m, is moving south with a speed 0.5v. If the cars have an inelastic collision, the final velocity of Car A is -v.
Solution:
Given:
Car A: Mass (m1)=m
Speed(v1)=v
Car B: Mass (m2)=2m
Speed(v2)=0.5v
Now, according to conservation of Linear Momentum:
If Car A, with mass m, is moving north with a speed v, collides, Car B,...
