A boat floats south on the Amazon River at a speed of 6 m/s. The boat and
passengers have a combined mass of 540 kg.
a. What is the momentum of the boat? (Remember, momentum is a vector
quantity.)
b. The passengers paddle backward, reducing the speed to 4 m/s. What was the
impulse applied to the boat by the paddling?

What would occur if the index of refraction of a material was less than n=1? the speed of light would increase to a speed larger than the maximum speed of light in a vacuum. the light wave would not bend at all though the material. the light wave would not be able to refract and would instead reflect off of the material. the speed of light would reduce to values close to 0 m/s.
