A beam of light in air strikes the surface of a smooth piece of plastic having an index of refractionof 1.55 at an angle with the normal of 20 degrees. The incident light has component E-field amplitudes parallel and perpendicular to the plane of incidence of 10.0 V/m and 20 V/m respectively. Determine the corresponding reflected field amplitudes.

Aracecar driver has to hold on tightly when going around a banked curve. approximately what is the centripetal force on a 2220.0 kg car going around a circle with a diameter of 190.0 meters at 25.0 m/s?

Acar traveling at a constant speed of 22.0 m/s passes a trooper hidden behind a billboard. one second after the speeding car passes the billboard, the trooper sets off in chase with a constant acceleration of 3.50 m/s2. how long does it take the trooper to overtake the speeding car? solve this problem by a graphical method. on the same graph, plot position versus time for the car and the trooper.

2) the sun is wonderful source of energy. it is renewable and natural with few dangers. solar cells rely on the sun for energy. these cells would be more practical to use if they were
