Harry was wishing for an easy physics test by tossing a 5.670 g quarter into a pond. He tossed the coin at a height of 1.20 meters above the surface of the pond, and the coin slowly sinks to the bottom of the 3.0 m deep pond. Calculate how long it takes for the coin to sink to the bottom if the buoyant force is 0.020 N
