The earth is 1.5 × 1011 m from the sun and takes a year to make one complete orbit. it rotates on its own axis once per day. it can be treated approximately as a uniform-density sphere of mass 6 × 1024 kg and radius 6.4 × 106 m (actually, its center has higher density than the rest of the planet, and the earth bulges out a bit at the equator). using this crude approximation, calculate the following.
a. what is vcm?
b. what is ktrans?
c. what is w, the angular speed of rotation around its own axis?
d. what is krot?
e. what is ktot?

the correct answer to the question is it has inertia.

explanation:

the splashing of water in the bottle can be explained in terms of inertia of motion.

from newton's first law of motion, we know that a body moving with uniform velocity along a straight line will keep on moving with the same velocity along that line unless and until it is compelled by some external unbalanced force. it is known as inertia of motion.

as per the question, the passenger is in the moving car. the open water bottle has the same velocity as that of passenger as he is holding the bottle.

when the car stops, the passenger will move in forward direction due to the inertia of motion. same also happens in case of water present in the bottle. the water splashed out as its inertia of motion is destroyed .
