Amountain climber jumps a crevasse of width w by leaping horizontally with speed v0. a) if the height difference between the two sides of the crevasse is h, what is the minimum value of v0 for the climber to land safely on the other side? express your answer in terms of the variables w, h, and appropriate constants. b) in this case, what is the climber's direction of motion on landing relative to the horizontal?

explanation:

speed of light in vacuum is 300,000 km/s

speed of light in other mediums is given by the expression v = c/n, where c is the speed of light in vacuum and n is the refractive index of medium.

for the first medium v = 200,000 km/s

  so, refractive index of medium = 300000/200000 = 1.5

    1.5 refractive index is usually for glass. so first medium is glass.

for the second medium v = 250,00 km/s

so, refractive index of medium = 300000/250000 = 1.2

    1.2 refractive index is usually for water. so second medium is water.

for the third medium v = 0 km/s

so, refractive index of medium = 300000/0 = ∞

    ∞ refractive index is usually for opaque mediums. so third medium is opaque medium.
