A ray of light strikes a flat, 2.00-cm-thick block of glass (n=1.50) at an angle of 30 degrees with respect to the normal. (a) Find the angle of refraction at the top surface.

A ray of light strikes a flat, 2.00-cm-thick block of glass (n=1.50) at an angle of 30 degrees with respect to the normal. (a) Find the angle of refraction at the top surface. (b) Find the angle of incidence at the bottom surface and the refracted angle. (c) Find the lateral distance by which the beam is shifted. (d) Calculate the speed of light in the glass and (e) the time required for the light to pass through the glass block. (f) Is the travel time through the block affected by the angle of incidence? Explain.
. A bullet leaves a rifle with a muzzle velocity of 521 m/s. While accelerating through the barrel of the rifle, the bullet moves a distance of 0.840 m. Determine the acceleration of the bullet (assume a uniform acceleration). B. Ima Hurryin is approaching a stoplight moving with a velocity of +30.0 m/s. The light turns yellow, and Ima applies the brakes and skids to a stop. If Ima’s acceleration is -8.00 m/s2, then determine the displacement of the car during the skidding process. (Note that the direction of the velocity and the acceleration vectors are denoted by a + and a – sign.)
Mileposts mark distance along a highway. A car traveled from milepost 15 to milepost 185. To calculate the average speed of the car, what additional information is necessary?
