Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?
Answer the question considering the information given in the image. Explain each step. a) Prove that the exit velocity of the water at point C is the same as that of an object in free fall that starts from the same height from the surface of the water to the ground (2 m). Hint: use Bernoulli's equation for points A and C.

In a manufacturing process, a drill press automatically drills a hole into a sheet metal part on a conveyor. In the drilling operation the drill bit starts at rest direcdly above the part, descends quickly, drills a hole, and quickly returns to the start position. The maximum vertical speed of the drill bit is 4 in./s, and while drilling the hole, it must move no more than 2.6 in./s to avoid warping the metal. Let s(t) be the drill biť's height (in inches) above the part as a function of time t in seconds. Sketch possible graphs of the drill bit's velocity [s'(t)] and acceleration [s"(t)].
