Aflat piece of glass covers the top of a vertical cylinder that is completely filled with water. if a ray of light traveling in the glass is incident on the interface with the water at an angle of 0a= 36.0 degrees , the ray refracted into the water makes an angle of 49.6 degrees with the normal to the interface. what is the smallest value of the incident angle 0a for which none of the ray refracts into the water? express your answer with the appropriate units.

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
