Consider two string- suspended balls, both with a mass of 0.15 Kilogram, one ball is pulled back in line with the other so it has a vertical height of 10 centimeter, and is then released.
a) Find the speed of the ball just before hitting the stationary one?
b) If the collision is completely inelastic, determine to what height do the balls swing?
