A27.0 g marble sliding to the right at 56.8 cm/s overtakes and collides elastically with a 13.5 g marble moving in the same direction at 14.2 cm/s. after the collision, the 13.5 g marble moves to the right at 71 cm/s. find the velocity of the 27.0 g marble after the collision.

Explanation:

Given

mass of marble

velocity of marble

mass of second marble

Velocity of second marble

After collision 13.5 gm marble moves to the right  at i.e.

Conserving momentum

first thing first of the answer is with technology. second thing second thing is that the big bang theory did not happened u see they say it did but what they dont realize is that like dinasures are still a round they might deny it but they and look at these 12 foot human skelteons they find lets see didnt the bible say something about giants. hope this peace.
