Atrain is slowing down with an average acceleration of -5.0 m/s2. ( negative sign shows deceleration ). if it’s an initial velocity is 50 mi./s how far does a travel in 6 seconds?

The train traveled 210 miles in 6 seconds of time duration.

Explanation:

The initial velocity of the train,u = 50 mile/s

Acceleration of the train ,a =

Duration of time ,t = 6 seconds

Using second equation of motion :

The train traveled 210 miles in 6 seconds of time duration.

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.
