What is its final kinetic energy
A proton is initially at rest at a point where the potential is 499 V. Some time later the proton is at a point where the potential is 211 V. If no force other than the electrostatic force acts on the proton, what is its final kinetic energy?.

A car is traveling at 55.0 km/h on a flat highway. (a) If the coefficient of friction between road and tires on a rainy day is 0.100, what is the minimum distance in which the car will stop?
While doing so it travels 117m in the +x direction and ends up with a velocity of +6.7m/s. What was the cars initial velocity?
A parallel-plate capacitor in air has a plate separation of 1.39 cm and a plate area of 25.0 cm2. The plates are charged to a potential difference of 255 V and disconnected from the source. The capacitor is then immersed in distilled water. Assume
Determine the state of polarization of left circularly polarized light after it is passed normally though: a) a quarter wave plate with horizontal fast axis; b) a half-wave plate with the fast axis at 45deg to horizontal; c) vertical linear polari
