A person throws a ball from height of 6 feet with an initial vertical velocity of 48 feet per second. Use the vertical motion model, h = -16t? + vt +s, where v is the initial velocity in feet per second and s is the height in feet, to calculate the amount of time the ball is in the air before it hits the ground again. Round your answer to the nearest tenth if necessary. Time in air: ___seconds

Explanation:

Recall the equation for time is distance divided by speed. Here you can use that to solve for "t".

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.
