Short Answer

A marble moving at strikes a marble at rest. What is the speed of each marble immediately after the collision?

Marvel of mass has speed .

Marvel of mass has speed

See the step by step solution

Step by Step Solution

Step 1: Given information

We have given,

Masses of marvel =

Speed of marvels =

We have to find their final velocity after collision.

Step 2: Simplify

The given Collison is a elastic collision.

In the elastic Collison the momentum and energy of the system is conserved.

Then conservation of momentum is,

Let us consider marvels as marvel 1 of and marvel 2 of

Then,

and

Then using conservation of energy,

Using equation (1) AND (2),
