A stone is thrown straight up from the ground with an initial speed of 33.2 m/s. At the same instant, a stone is dropped from a height of h meters above ground level. The two stones strike the ground simultaneously. Find the height h. The acceleration of
gravity is 9.8 m/s.
Answer in units of m.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
