A 1.8kg physics cart is initially traveling 2.8m/s when it collides with an ideal spring
(with a spring constant of 710N/m and natural length shown. The final time is
defined as when the spring at maximum compression and the cart is about to
rebound backwards. Neglect loss.
List the energy types at the initial and final time and whether work and loss (due to non-
conservative forces) occur as well as the corresponding amounts of energy.
