A5-lb ball is dropped from a stationary boat so that it strikes the surface of a lake with a speed of 16fi/s. while dreopping to the bottom of the lake the ball experiences a drag force that is proportional to the velocity. it is known that the terminal speed of the ball is 40.322f/s. find: a) constant for the drag, c)depth of the lake and th of the lake, if it takes 4 seconds for the ball to reach the bottom of the lake. an expression for the acceleration of the ball, b) the proportionality e speed of the ball when it hits the bottom of the lake.
