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 swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 4.00 m/s, and her takeoff point is 1.70 m above the pool. (a)How long (in s) are her feet in the air? (b)What is her highest point (in m) above the board? (c) What is her velocity (in m/s) when her feet hit the water?

A swimmer bounces straight up from a diving board and falls feet first into a pool. She starts with a velocity of 3.00 m/s, and her takeoff point is 1.70 m above the pool. How long (in s) are her feet in the air? What is her highest point (in m) above the board? What is her velocity (in m/s) when her feet hit the water?

The diver has a mass of 50 kg (a) What is the value and direction of the force each bracket exerts on the diving board (b) If the diver backs away from the edge of the diving board, what will happen to these two forces? Justify your answer. (c) If the bars...

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...

A diver (m = 60 kg) jumps from a diving board. At takeoff, his angular momentum about the transverse axis is 30 kg⋅m2/s. His radius of gyration about the transverse axis is 0.5 m at this instant. During the dive, he tucks and reduces his radius of gyrations about the transverse axis to 0.2 m. After he tucks the body, what is his angular velocity about the transverse axis? A.) 12.5 rad/s B.) 1 rad/s C.) 2.5 rad/s D.) 10...

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...
