Questions
1. Students can use the Smart Cursor to find the velocity and acceleration of the cart just
before the collision.
2. During the collision, the velocity moves from positive, through zero, to negative. When the
velocity is negative, the cart is moving in the opposite direction.
3. During the collision, the acceleration varies from zero to negative and then back to zero as
the cart rebounds in the opposite direction.
