Question

When you catch a water balloon, it's best to start with your hand in motion, moving with the balloon, and then gradually slow it to rest.?

Answer 1

Step-by-step explanation:

Let's explain it with the newton second law which that the rate of change of momentum is equals to applied force.

Mathematically:

`F = (dp)/(dt)`

It's the force we applied in order to stop the baloon. Force is inversely propertional to the time interval. So if we want to decrease the force then we have to increase the time interval which we do by the motion of the hand.

So we can conclude that to increase the time of contact with the baloon we reduce the force and prevent the baloon from bouncing off the hands.
