Abilliard ball travels 20 cm in the positive direction, hits the cushion and rebounds in the negative direction, and finally comes to rest 6.0 cm behind its original position. what is the distance?

Explanation:

Given that

the ball travelled in positive direction x1 = 20 cm

the ball comes to stop at a distance = x2 = 6 cm

the distance travelled in -ve direction

x3 = x1 - x2 = 20- 6 = 14 cm

total distance co=vered by the given ball

x = x1 +x3 = 20+14 = 34 cm

x = 34 cm

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

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.
