Hello!

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object?

We have the following data:  

KE (Kinetic Energy) = 480 J

m (mass) = ? (in Kg)

v (speed) = 8 m/s  

Formula to calculate kinetic energy:  

Solving:  

15 kg

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.

not too sure thinking all accelerations are pointed down
