A coin is tossed. If the outcome is a head, a die is thrown. If the die shows up an even number, the die is thrown again.
When a coin is tossed, the possible outcomes are head (H) and tail (T). When a die is thrown, the possible outcomes are 1, 2, 3, 4, 5, or 6. Thus, the...

A heavy stone is thrown from a cliff of height h with a speed v.
(d) the speed does not depend on the initial direction. Explanation:- When the stone is thrown its total mechanical energy = K.E.+P.E. = ½mv² + mgh ---------(i) This energy is conserved and when near the ground...
