How much kinetic energy does a 2 kg book falling out of the backpack with a velocity of 4 m/s have?

E = 16 J

Explanation:

Given that,

Mass of a book, m = 2 kg

Velocity of the book from the backpack, v = 4 m/s

We need to find the kinetic energy of the book falling out of the backpack. Due to the motion of the object, kinetic energy is possessed by it. It can be given by :

So, the kinetic energy of the book is 16 J.

step-by-step explanation:

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.
