Starting with the initial speed of 5.00 m/s at the height of 0.255 m, 1.65-kg ball swings downward and strikes 4.75-kg ball which is at rest, as drawing shows.
Starting with initial speed of 5.00 m/s
i) Using principle of conservation of mechanical energy, determine speed of 1.65-kg ball just before impact.
ii) Suppose that collision is elastic, determine velocities (magnitude and direction) of both balls just after collision.
iii) How high each ball swings after collision, ignoring air resistance?
