A1000-kg car traveling east at 20 m/s collides with a 1500-kg car traveling west at 10 m/s. the cars stick together after the collision. what is the common velocity of the cars after the collision?

Common velocity will be 2 m/sec

Explanation:

We have given a car of mass 1000 kg is traveling in east at 20 m /sec

So and ( take east direction as positive )

And another car of mass 1500 kg is moving with 10 m/sec in west direction

So and ( west direction will be negative direction )

According to law of conservation of momentum

So common velocity will be 2 m/sec

explanation:

areas w steep slopes, west coast, rocky mountains, and appalachian mountains

i would think it's food chain
