(e) Suppose in a repeat experiment that the carts are altered so that a magnetic repulsion system is in place between the two carts. Now, instead of Cart A sticking to Cart B, Cart A comes to rest entirely after the collision. In this new experiment, the time t for Cart B to travel between the gates will be...
a) Greater b) Smaller c) The same
Justify your response with an explanation.
Answer: b) Smaller
All momentun of cart A is transferred to cart B in this case. The speed of cart B will be greater than in the first case.
