Problem 46

A basketball player is running at 5.00 m/s directly toward the basket when he jumps into the air to dunk the ball. He maintains his horizontal velocity. (a) What vertical velocity does he need to rise 0.750 m above the floor? (b) How far from the basket (measured in the horizontal direction) must he start his jump to reach his maximum height at the same time as he reaches the basket?

Step-by-Step Solution:
Step 1 of 3

 The Endocrine System  1. Regulating metabolism and water and electrolyte balance  2. Adaptive changes to help the body cope with stress  3. Growth and development  4. Controlling reproduction  5. Regulating red blood cell production  6. Digestion and absorption  Complexity of Hormones  A single gland can release multiple hormones  A single hormone may be secreted by more than one gland  A single hormone can have more than one target  A hormone may be released at different rates over time  A single target cell may be influenced by more than one hormone  Complexity of Hormones (continued)  The same chemical messenger may be considered a hormone or a neurotransmitter depending on how it is released and where it acts  Some organs only release hormones  Classifications of Hormones  Protein or Peptide hormones  Made from two or more amino acids  Majority of all hormones  Dissolved in and carried by the plasma  Steroid Hormones  Made from cholesterol  Transported in the plasma bound to plasma proteins  Amine Hormones  Derived from tyrosine  Can be, in the case of catecholamines, both dissolved in plasma and bound to plasma proteins  Activation by Hormones  Hydrophilic (water loving) hormones  Act through second messenger pathways  G-protein receptors  Lipophilic (lipid loving) hormones  Enhance synthesis of enzymatic or structural proteins  Act on receptors inside the cell, commonly in the nucleus  Hormone with receptor binds to DNA
