Two identical steel balls, each of mass 2.9 kg, are suspended fromstrings of length 30 cm so that they touch when in theirequilibrium position. We pull one of the balls back until itsstring makes an angle of ? = 37° with the vertical and let it go.It collides elastically with the other ball.
a) How high will the other ball rise?
b) Suppose that instead of steel balls we use putty balls. Theywill collide inelastically and remain stuck together after thecollision. How high will the balls rise after the collision?
