Answer:

+2.5 m/s and -2.5 m/s

Explanation:

There are two possibilities:

1) The velocity lies in the IV quadrant, with y being negative and x being positive. In this case, the magnitude of the horizontal component is

v_x = v cos 60^{\circ} = (5.0 m/s) cos 60^{\circ} =2.5 m/s

2) The velocity lies in the III quadrant, with y being negative and x being negative as well. In this case, the magnitude of the horizontal component is

v_x = -v cos 60^{\circ} = -(5.0 m/s) cos 60^{\circ} =-2.5 m/s

Explain why mess extinctions occur and why it make sense to measure geologic time between mass extinctions
Nastasia [14]
Mass extinction occur from natural disasters, such as a n asteroid hitting earth or a volcano errupting and spread ash everywhere.

It makes sense to measure geologic time between mass extinctions because after each mass extinction, there is almost no life left and the few left have to repopulate, which may lead way to new mutations and new varieties of plants and animals.

What happens to the ray of light when it travels from glass to water?
vodomira [7]

Glass and water are thicker and heavier than air. They are said to be 'denser' than air. What happens is that light slows down when it passes from the less dense air into the denser glass or water. This slowing down of the ray of light also causes the ray of light to change direction.
