Problem 11.023 - Dropped ball: Acceleration as a function of velocity NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A ball is dropped from a boat so that it strikes the surface of a lake with a speed of 16.5 ft/s. While in the water, the ball experiences an acceleration of a = 10−0.8 v, where a and v are expressed in ft/s2 and ft/s, respectively. The ball takes 3.9 s to reach the bottom of the lake. Problem 11.023. a - Depth of lake: Obtaining velocity from acceleration, and position from velocity, by integration Determine the depth of the lake. The depth of the lake is ft. Problem 11.023. b - Speed at bottom: Obtaining velocity from acceleration by integration Determine the speed of the ball when it hits the bottom of the lake. The speed of the ball is ft/s.

A ball is attached to a cord of length L, which is tied to a frame attached to a truck bed as shown in figure (a), below.
