Question

1.     Picture an elastic collision between two carts of equal mass. Cart A is at rest, and cart B is moving at velocity V.  What is the final velocity of cart A and of cart B?

2.     Picture now an inelastic collision between two carts of equal mass. Cart A is at rest, and cart B is moving at velocity W. What is the final velocity of cart A and of cart B?

3.     An explosion (see attached lab manual pdf for description) occurs between two cart, not necessarily of equal mass. What is the sum of their momenta?

Explanation / Answer

1)as the two carts have same mass and the collision is elastic,

the velocities are interchanged

VA = V and

VB = 0

2)


3) initial is momentum is zero. so, final momentum of the system should be equal to zero.
