Two balls, of masses ma= 36 g and mb= 68 g are suspended from the horizontal on a string 30 cm. Ball a is pulled away from ball b at an angle of 60 degrees with the vertical and released.
a) what is the velocity of the lighter ball before impact? (the right is positive)
b) what is the velocity of each ball after the elastic collision?
ball a:
ball b:
c) what will be the maximum height of each ball (above the collision point) after the elastic collision?
ball a:
ball b:
