For an experiment, I threw a softball and measured the height I threw it at, the time before it landed, and the distance. How would I solve for Initial Velocity, Throw Angle, and Max Height? time = 1.2s
distance = 7.26m
starting height = 2m

The free body diagram shows a box being pulled to the left up a 25-degree incline. the magnitude of the normal force is

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
