A small block is released from rest at the top of a frictionless incline. The block travels a distance 0.633 m in the first second after it is released. How far does it travel in the next second

1.89 m

Explanation:

Given

Block travels in first second

It is released from rest i.e. initial speed is zero (u=0)

using

where a=acceleration

here acceleration is the component of gravity on incline plane (say )

so

So distance traveled in

So distance traveled in is

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.
