Х Unit test IH Sum A cart is pushed into a short spring and then released from rest. The cart follows the pathway shown in the diagram below and passes through positions 1-4. The spring only touches the cart at the first position, the cart has no height at position 3, and the cart reaches a maximum height at the last position. The height of zero (y = 0) is marked on the diagram below. There is no significant friction within the car or between the car and track. Click each dot on the image to select all answers that apply. Choices: KU, U. (4) v=0 avitation se va (2 ) v=0 svou WW (3) y=0 Select the types of energy present (non-zero) for the cart-Earth-spring system as the cart is at each of the four positions (1-4) shown in the diagram.
