1) A ray of light is traveling in a medium of index 1.42 and is incident on a medium of index 1.5. What is the smallest incident angle that will result in no refraction, i. e. what
incident angle gives a 90° refraction angle?

2) a ray of light traveling through glass with an index of a fraction. n = 1.5 strikes the interphase of the glass water. Let the index of refraction of water be n=1.33. At what angle does the ray not enter the water?

The rocket is fired vertically and tracked by the radar station shown. when θ reaches 66°, other corresponding measurements give the values r = 32700 ft, r¨ = 85 ft/sec2, and θ˙ = 0.019 rad/sec. calculate the magnitudes of the velocity and acceleration of the rocket at this position.
