Equation [3], conservation of momentum, is used to find the initial velocity of the ball, Vb. The velocity of the pendulum-ball, Vf, is taken from the velocity v found in question 1 . The pendulum, mp, is initially at rest, and mb is the mass of the ball. Using equation [3], determine an equation to solve for the velocity of the ball, Vb, in terms of mb, m and Vf

the closer the planet is to the sun, the larger the gravity

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.
