Question 05/97

When you throw a stone at a glancing angle into the water it skips several times before sinking. Can you increase the number of skips by modifying the angle or velocity at which the stone is thrown? Can you increase it by choosing a stone of special weight or shape? Is there a limit to the number of skips?

p.s. This problem is suggested towards your summer vacation. You may try an experimental approach...
