Suppose that a motorboat is moving at 49 ft/s when its motor suddenly quits, and that 9 s later the boat has slowed to 28 ft/s. Assume that the resistance it encounters while coasting is proportional to its velocity, so that dv/dt = - kv. How far will the boat coast in all? The boat will coast feet. (Round to the nearest whole number as needed.)
