CSI discovers a car at the bottom of an 95 m cliff. The car had landed 34 m from the cliff’s edge? Draw a diagram with all variables involved. Create a table of the X and Y components. Show all equations and all math required to answer the next two questions. Take a picture of your work and upload the file. Make sure to round to two decimal places and include correct units on your final answer. A. How fast was the car going when it went off the cliff? B. The driver inside forgot to wear his seat belt, how much time did he have to react before the car hit the ground?

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

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.
