1. non-uniformly charged hollow cylinder (double points problem) consider an infinitely long charged hollow cylindrical object with outer radius 4a and inner radius a. let the axis of the cylindrical object be the z axis. between r = a and r = 4a, the charge per unit volume is rho(r) = rho0( 4r a − r 2 a 2 − 3) where rho0 > 0 is a constant. (a) sketch a plot showing rho(r) vs r. on the vertical axis, label the values of rho(r) at r = a, r = 2a, r = 3a, and r = 4a. (b) calculate the electric field e~ (~r) at all points in space. (you may need to write different expressions for different regions.)

You have been called to testify as an expert witness in a trial involving a head-on collision. car a weighs 1515 lb and was traveling eastward. car b weighs 1125 lb and was traveling westward at 44.0 mph. the cars locked bumpers and slid eastward with their wheels locked for 22.5 ft before stopping. you have measured the coefficient of kinetic friction between the tires and the pavement to be 0.750 . how fast (in miles per hour) was car a traveling just before the collision? (this problem uses english units because they would be used in a u.s. legal proceeding.)
