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.

Acatapult is tested by roman legionnaires. they tabulate the results in a papyrus and 2000 years later the archaeological team reads (distances translated into modern units): range = 0.4 km; angle of launch = π/5 rad; landing height = launch height. what is the initial velocity of launch of the boulders if air resistance is negligible?

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
