A thief throws a ring down at his partner at 4.0 m/s. It is 9.0 m to the partner’s hands. a) Find the velocity of the ring when the partner catches it.

b) How long will it take for the ring to pass between the two crooks?

a) Vf = 13.87[m/s]

b) t = 1 [s]

Explanation:

a)

To solve this problem we can use kinematics equations:

where:

Vf = final velocity [m/s]

Vi = initial velocity = 4 [m/s]

h = elevation = 9 [m]

g = gravity acceleration = 9.81 [m/s^2]

b)

Now using the next equation we can find the time

the answer is b

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.
