Impulse-Momentum theorem. For a given amount of momentum change, clearly describe a situation where you would want to have the time interval extended to minimize the acting force and where you would want the time interval shortened to maximize the acting force.
Homework Answers
If I jump from any height, I will bend my knee upon impact, to extend the time of collision to minimize the acting force.
While playing billiards, it is desired that the cue ball hits the object ball for a short interval so as to maximize the acting force.

Learning Goal: To understand
the relationship between force, impulse, and momentum. The effect
of a net force ΣF⃗ acting on an object is related both to the force
and to the total time the force acts on the object. The physical
quantity impulse J⃗ is a measure of both these effects. For a
constant net force, the impulse is given by J⃗ =F⃗ Δt. The impulse
is a vector pointing in the same direction as the force vector. The

To apply the principle of angular impulse and momentum to
describe a particle's motion.
The moment of a force about a point O, fixed in an
inertial coordinate system, MO, and the angular momentum about the
same point, HO, are related as follows:
∑MO=H˙O
where H˙O is the time derivative of the angular momentum,
HO=r×mv. Integrating this equation with respect to time yields the
following equation:
∑∫t2t1MO dt=(HO)2−(HO)1
This equation is the principle of angular impulse and momentum,
and it...

Describe a situation from your own life where you used both creative and critical thinking to come to a decision. How did your decision-making skills benefit from using these two types of thinking? Using the same situation, consider how your family members or friends would have viewed and dealt with the situation.

Describe a situation in which you would test a directional hypothesis. Be sure to state the independent variables (e.g., drug or placebo) and the dependent variables (e.g., weight loss) clearly and explain why the hypothesis is directional. Then, revise the same situation to make it nondirectional. Explain which according to you is more appropriate and why. Evaluate the practice of altering the alpha level so that a two-tailed test will have a 5% rejection region on both sides of the...
