A small object can have a large momentum as long as the speed is very high. A bullet is very light but has a lot of momentum because of the enormous speed when shot out of a gun. However if you merely toss the bullet by hand, the momentum is very small when compared with the shot bullet.

A heavy object can have a small momentum but the heavier the object gets the greater the momentum. A very heavy object will still have more momentum than something light moving at the same speed but the heavy object will be much harder to move. So yes, a large object can indeed have a small momentum. If a 200lb block is moving at 0.0005m/s it has a very small momentum when compared with a bullet that weighs .5lb moving at 200m/s.

The mini cooper would have to be moving faster to have the same momentum. The cadillac would have to be slower because of the fact that momentum equals mass x velocity. The cadillac has a larger mass so the velocity would have to be slower than the mini cooper to have the same momentum. If the mini weighed in at 1500lbs and was moving 2m/s, the momentum would be equal to the 3000lb cadillac only when it is moving at a velocity of 1m/s. So therefore if we witnessed the cars with the same momentum, the mini would be moving faster than the cadillac.
