In a physics demonstration, two rubber balls are dropped down a tube towards the ground,with the lighter ball behind, and not quite in contact with, the heavier ball. The heavier ball collides with the ground and bounces, then collides with the still descending lighter ball. Assume that all the collisions are elastic. In one such demonstration, the heavier ball has a mass of 500 g, the lighter one a mass of100 g, and they are released 1.00 m above the ground. How high does the light ball rise after the two collisions?
Find time constant if the ball's amplitude has decreased to 2.20 cm after 51.0 oscillations? Explain your answer.
A cork on the surface of a pond bobs up and down two times per second on ripples having a wavelength of 8.80 cm. If the cork is 13.5 m from shore, how long does it take a ripple passing the cork to reach the shore?
