<div class="wp-block-create-block-problemblock">In a rescue attempt, a hovering helicopter drops a life preserver to a swimmer being swept downstream by a river current of a constant velocity v.  The helicopter is at a height of 9.8 m.  The swimmer is 6.0 m upstream from a point directly under the helicopter when the life preserver is released.  It lands 2.0 m in front of the swimmer.  How fast is the current flowing?  Neglect air resistance.<ul><li>13.7 m/s</li><li>9.8 m/s</li><li>6.3 m/s</li><li>2.8 m/s</li></ul></div>
