To catch a water-filled balloon without breaking it, people allow their hands to move with the balloon upon catching it. This works because
a) the balloon's momentum changes more slowly
b) there is less force applied
c) there is less impulse
d) both A and C are true
e) all of A, B and C are true
a and b are true
impulse is the total change of momentum which is the same for all ways of stopping it break or not.
e) all of A, B and C are true
Well, that's quite the show for a water-filled balloon! It's like a delicate dance with some physics thrown in. When people allow their hands to move with the balloon upon catching it, the balloon's momentum changes more slowly, which helps reduce the force and impulse applied to it. So, you get a picture-perfect catch without breaking it! Just remember to keep your clown shoes dry while you're at it.
The correct answer is d) both A and C are true.
When people allow their hands to move with the balloon upon catching it, it helps reduce the force and change in momentum of the water-filled balloon, thereby minimizing the risk of the balloon breaking upon impact.
Option a) states that the balloon's momentum changes more slowly, which is true. By allowing their hands to move with the balloon, people extend the time it takes for the balloon's momentum to change, reducing the force applied to the balloon and decreasing the chances of it breaking.
Option c) states that there is less impulse, which is also true. Impulse is the change in momentum, and by allowing their hands to move with the balloon, the change in momentum of the water-filled balloon is reduced. This means there is less impulse acting on the balloon, which helps prevent it from breaking.
Therefore, both statements A and C are true, making option d) the correct answer.
To catch a water-filled balloon without breaking it, people allow their hands to move with the balloon upon catching it. This technique works because both the balloon's momentum changes more slowly and there is less impulse applied. Therefore, the correct answer is:
d) both A and C are true.
Explanation:
a) The balloon's momentum changes more slowly: When a water-filled balloon is thrown towards you, it possesses momentum, which is determined by its mass and velocity. If you were to abruptly stop the balloon, its momentum would change rapidly, potentially causing the balloon to burst. By allowing your hands to move with the balloon, you extend the time over which the momentum changes, reducing the force exerted on the balloon.
c) There is less impulse: Impulse is the change in momentum, and it is equal to the force applied multiplied by the time over which the force is exerted. By extending the time taken to catch the balloon, you reduce the force applied, which in turn decreases the impulse. This helps prevent the balloon from bursting.
Therefore, by allowing your hands to move with the water-filled balloon, you slow down the change in momentum, reduce the force applied, and minimize the impulse acting on the balloon. This increases the chances of successfully catching the balloon without breaking it.
