A white go-kart moving 5 m/s hits a red go-kart that is at rest. Both go-karts weigh 2 kilograms and the white go-kart travels in the opposite direction at 2 m/s after the collision. What is the velocity of the red
go-kart after the collision?
A 10 m/s
7 m/s
5 m/s
o 2 m/s

it is very well related to a lot of things but with my limited knowledge i can confidently say that the answer is space.

double the distance = divide strength by 4

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.
