...i was walking on the road and a girl is coming from opposite direction..something hits the ground between us and water spread out..it was a water filled balloon..which just missed it target(guess who is the target!!)...while i coverd some steps.. i started thinking, how this ballonn got ruptured(ahhh u throw something on ground it will break or crash)..yeah that is ok...but why does it rapture...why..
so i analyze the condition by making free body diagram....while i took the bus from peeragadhi to uttamnagar...so i m seeing this that there is this balloon filled with water and it is in the hand of it thrower..thrower throws it with a force..this force compels the balloon to move in the direction of the target....during its jouney through air, the frictional force due to air(this is minimal) and gravitational force get applies on it...when the balloon touch the ground, there is gravitational force downward and the normal force upward, and ofcource frictianl force on the balloons surface, now due these opposite forces the balloon get expanded...so what??.. a gas filled balloon when hit the ground expanded, even a tennis ball get expanded at the time it hits the ground...but what is wrong with this water filled balloon...why does it burst out....
