Abored student makes a poor life decision and decides to go do donuts in a school parking lot. the student jumps into his/her 1500kg car and heads to the lot. assume he/she drives in circles with a 10 meter radius and the coefficient of friction is 0.7 between the tires and the dry road. a) what is the maximum speed car can go before it starts to slide?

Using the work energy theorem. what is the velocity of a 850kg car after starting at rest when 13,000j of work is done to it.

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.
