HELP PLEAS A car is traveling at 9 m/s It decelerates at a rate of -3.3m/s It weighs 1600kg. What is the friction coefficient of the car

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?

Aball has an initial velocity of 3 m/s. if there is no friction, what is the highest it could roll?

How will the system respond to a temperature increase?
