Two cars are travelling in the same direction along a street. Car A collides with Car B and they lock together. Calculate tgeur velocity after the collision.
Before: Car A: mass of 1001kg.
Velocity of 12m/s
Car B: mass of 1200kg
Velocity of 10m/s
After: V=?

momentum is conserved.
original momentum=final mometum
MassA*Va+MassB*Vb=(MassA+MassB)V
