The point of the homework is for you to learn enough about refraction to answer this yourself. Otherwise, the teacher could just answer her own question and not bother assigning it to you.

very simple problem. use snell's law. . look it up in your textbook or online.
sin(angle1)*(index of refraction1)=sin(angle2)*(index of refraction 2)
my apologies, I underestimated the problem. basically, the answer to this question is that there is no angle of refraction, the light is completely reflected. The glass acts as a mirror.

Acceleration = rigidity / mass. speed = acceleration * time. means = rigidity * speed #a million assume uniform rigidity at each and every section. in the blocks, the acceleration = 5/0.2 = 20m/s² rigidity = 20*70 = a million,400N Out of the blocks, acceleration = (12-5)/5 = 7/5m/s² rigidity = 7/5*70 = 98N favourite means = ninety 8*(12+5)/2 = 833W #2 Conservation of skill. assume gravity = 10 m/s² (you should use 9.80 one in case you want and also you've were given a calculator) skill skill at 100m relative to the floor = 10 * one hundred * 3 = 3,000J skill skill at 50m = a million,500J Kinetic skill at 50m = a million,500J you are able to calculate its speed from this: 31.6 m/s
