A puck slides across a smooth, level tabletop at height H at a constant speed vo. It slides off the edge of the table and hits the floor a distance x away as shown in the figure. What is the algebraic relationship between the distances x and H?
A 3.1 kg dog stands on a 15.00 kg flatboat at distance D = 6.1 m from the shore. It walks 2.00 m along the boat toward shore and then stops. Assume no friction between the boat and the water, find how far the dog is then from the shore.
