A 1000-kg car collides head-on with a 2500-kg van that is initially traveling at 20 m/s. The two vehicles stick together and come to rest immediately as a result of the collision. Calculate the initial speed of the car. PLS EXPLAIN HOW ALSO

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:

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
