Q1. Charge is scattered uniformly throughout a long cylindrical shell of inner radius R and out radius 2R. At what radius is the electric field equal to one-half the value on the outer surface?
Q2. A car in stop-and-go traffic starts at rest, moves forward 17 in 9.0, and then comes to rest again. The velocity-versus-time plot for this car. What distance does the car cover in the first 5.0 seconds of its motion? What distance does the car cover in the last 3.0 seconds of its motion? What is the constant speed that characterizes the middle portion of its motion?
At one instant a bicyclist is 49.0 m due east of a park's flagpole, going due south with a speed of 14m/s. Then 35.0 s later, the cyclist is 49.0 m due north of the flagpole, going due east with a speed of 14m/s.
