Semester 2 PE Fitness Reflections

What was the most interesting topic you learned about PE this semester? Why did it stand out to you?
How would you describe your overall fitness level (Out of Shape/Beginner, Intermediate, Advance) now compared to first semester? Did you notice any improvement in your health or endurance by completing your 20 minutes of PE activity each day? Did you see any growth or improvement from first semester? Explain with details.
What do you want to improve on to increase your physical fitness over the summer? How do you plan to do it? Explain with details. THIS IS A PROJECT AND I NEED A GOOD GRADE

Light that is polarized along the vertical direction is incident on a sheet of polarizing material. only 96% of the intensity of the light passes through the sheet and strikes a second sheet of polarizing material. no light passes through the second sheet. what angle does the transmission axis of the second sheet make with the vertical?

Astudent throws a water balloon with speed v0 from a height h = 1.76 m at an angle θ = 21° above the horizontal toward a target on the ground. the target is located a horizontal distance d = 9.5 m from the student’s feet. assume that the balloon moves without air resistance. use a cartesian coordinate system with the origin at the balloon's initial position. (a) what is the position vector, rtarge t, that originates from the balloon's original position and terminates at the target? put this in terms of h and d, and represent it as a vector using i and j. (b) in terms of the variables in the problem, determine the time, t, after the launch it takes the balloon to reach the target. your answer should not include h. (c) create an expression for the balloon's vertical position as a function of time, y(t), in terms of t, vo, g, and θ. (d) determine the magnitude of the balloon's initial velocity, v0, in meters per second, by eliminating t from the previous two expressions.

Describe how the motion of a spring being pushed forward and backward is similar to the motion of air particles in a sound wave.
