In an exciting game, a baseball player manages to slide safely into second base. the mass of the player is 80.9 kg and the coefficient of kinetic friction between the ground and the player is .48
a. find the magnitude of the frictional force
b. if the player takes 1.4s to come to rest what was his initial velocity

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.
