Light shone from a mystery material into water undergoes total internal reflection at an angle of 33.4 degrees.
a) What is the index of refraction of the mystery material?
b) Use part a to identify the material.
A particular freely falling object requires 1.95 s to travel the last 33.5 m before it hits the ground. From what height above the ground did it fall.
A car takes 11 s to go from v = 0 to v = 75 m/s at approximately constant acceleration. If you wish to find the distance travelled using equation d = 1/2 at2, what value should you use for a.
