An automobile travelling on a straight, level road has an initial speed v when the brakes are applied. In coming to rest with a constant acceleration, it travels a distance x.

A beam of white light enters a prism of crown glass (n = 1.5) from air (n = 1.00). Once inside, the colors in the light disperse. The white light enters at an angle of 51 degrees. The blue light inside refracts at 19.5 degrees once inside the glass.
