Earth's gravity accelerates objects at 9.8 m/s2. when the flying object reaches the top of its arc (even if it is not pictured), it has a vertical velocity of 0 m/s. ignoring air resistance, what would be the vertical velocity of the object after 1 second?

Write the equation for momentum, first using symbols for the variables, then using words for the variables.

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?
