2. A diver bounces straight up from a diving board, avoiding the diving board on the way down, and falls feet first into a pool. She starts with a velocity of 4.00 m/s upward, and her takeoff point is 1.80 m above the pool. (a) What is her highest point above the board? (b) How long a time are her feet in the air? (c) What is her velocity when her feet hit the water?

A 2.18-m-long diving board of mass 13.2 kg is 3.00 m above the water. It has two attachments holding it in place. One is located at the very back end of the board, and the other is 25.0 cm away from that end. (a) Assuming that the board has uniform density, find the force acting on each attachment. {435 N, upward, 565 N, downward} b) If a diver of mass 69.3 kg is standing on the front end, what are...

Only point A please
HOMEWORK 1: At the Cullowhee Zoo one of the most popular attractions is watching the hippos dive off of a specially constructed diving board into the Tuckaseegee River. They are magnificent, you should really go some time. The diving board consists of a very strong wall with a support pipe embedded into it with very strong concrete. The pipe is welded together with a diving board that has a hollow, rectangular cross section. BOTH THE PIPE...

Consider the free-body diagram of a person holding a ball with their arm extended horizontally, as shown below on the left. The ball weighs WB 30 N, and is held at a distance d0.35 m from the elbow (E). The lower arm weighs WA 10N, with the center of mass distance 1- 0.15 m away from E. The biceps muscle applies a vertical upward force B to the lower arm at distance s - 0.03 m from E. a) What...

(21 pts.) Two people are on a row boat out in the middle of a calm lake. Initially the boat and the people in the boat are at rest. The people, who are good swimmers, are standing in the boat and decide to race to shore. Since they are roughly in the middle of the lake, they decide to swim in opposite directions from one another. The people simultaneously dive from opposite ends of the boat. Person A, who weighs...
