Assume that the conditions are as in except that there is a force due to air resistance of v2/1325, where the velocity v is measured in m/s. (a) Find the maximum height above the ground that the ball reaches. (b) Find the time that the ball hits the ground. (c) Plot the graphs of velocity and position versus time. Compare these graphs with the corresponding ones in 20 and 21
B. Spongy (cancellous) Bone 1. Contains many, larger “holes” filled with red bone marrow, which is the site of blood production in adults. 2. No haversian systems. 3. Contain trabeculae which are the actual bony walls between the holes. 4. Makes bone lighter. 5. Found in flat and many irregular bones and at the epiphyses of long bones. VI. Bone formation (ossification) and bone break down (remodeling) A. Ossification – is the process of forming bone in the body.
