Two cars each of mass 1000kgare moving in a straight line but in opposite directions. The velocity of each car is 5m/s before the collision during which they stick together. What will be the velocity of the combined cars after collision?

Since both cars have the same mass and same initial velocity, they will have the same momentum.
On collision, they cancel out each other's momentum, which means final momentum is zero, therefore velocity will be zero
