6. A daredevil wants to jump a motorcycle off of a 30° ramp. How much applied force would the engine have to provide to the motorcycle in order in order to give
the bike and rider (combined mass of 250kg) an acceleration of 3.27 m/s2 at the
end of the ramp? The ramp provides a constant frictional force of 1000N.

the answer to your question is high voltage and high currency

50 inches should be the resultant vector

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.
