Describe two ways you can improve gait speed. Which has the greater speed, 10m/sec or -20m/sec? Why? List the three variables that determine projectile motion. Which one do you have the most control over? Why? Which one has the biggest impact? Why? What did you find interesting and/or new after reading these 2 chapters in the textbook?
when the angular velocity of a balanced rotating body increase it can lose its balance true or false?
The angular velocity W of a rotating solid body is a vector whose magnitude is the rate angular displacement (radians per second) and whose direction is that in which aright-handedscrew would advance if turned in the same direction. The position vector r of a point is the vector from the origin of coordinates to the point. Show that the velocity of any point in rotating solid body v=[W×r], relative to an origin located on the axis of rotation.

Question C1. Give two (2) ways in which you can increase the yield strength of a metal and briefly explain how each works to increase the yield stress. Question C2. An aluminium-Silicon casting alloy has a composition that is close to the Al-Si eutectic composition. Give two reasons why this composition is used to cast aluminium based engine blocks Question C3. Describe briefly three (3) mechanisms by which short randomly aligned fibres add to the toughness of a composite. can...
You are working out and you quickly feel your body temperature spike to a point that you are unable to continue to exercise. Identify the regulated step in glycolysis that has a direct impact on body temperature, explain why, what other effects occur if this step is not regulated, and ways to both activate and inhibit this enzyme.
list at least two ways you think the physician-patient relationship can be improved. Can you provide a first-hand example/experience (while maintaining privacy!) ?
Analysis In java, a List can be implemented in a number of ways. Compare and contrast an ArrayList and a LinkedLists. In which situations would you use one to implement a List over another? (explain in runtime on add and remove, memory usage, and get/set.)
Explain two ways in which an air bag changes the force on your body to make you safer during a collision. How can you use Newton's force laws to explain the way a rocket works? Be as specific as you can. How would you describe the way a rocket works using the concept of momentum?
