Car p travels due east along a straight highway at a constant speed of 30 m/s. at 9: 00 a. m., p passes exit 17. at precisely the same moment, car q passes exit 16, traveling due west at a constant 26 m/s. slightly later, car p and car q pass the same point. knowing the exits are exactly 7 km apart, how many minutes past 9: 00 a. m. do the cars pass each other?

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

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?
