You’re still in a redecorating mood and want to move a 35kg bookcase to a different place in the living room. you exert 58 n on it which makes it move at 0.12 m/s^2. find the coefficient of kinetic friction between the bookcase and the carpet

0.16

Explanation:

Newton's second law states that the resultant of the forces exerted on the bookcase is equal to the product between the mass (m) and the acceleration (a):

where

F = 58 N is the force applied

Ff is the frictional force

Substituting, we find the frictional force

The frictional force has the form:

where is the coefficient of kinetic friction. Re-arranging the formula, we can find the coefficient:

mass and volume are the answers you are looking for

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.
