A student is experimenting with two sets of balls colliding in a closed system.
In the first trial, two hard balls collide for 0.01 seconds.
In the second trial, two softer balls collide for 0.02 seconds.
The amount of force applied to each set of balls is equal.
Which statement is correct about these trials?
(1 point)
The momentum in the first trial is twice the impulse in the second trial.
The impulse in the first trial is half the impulse in the second trial.
The impulse in the first trial is twice the impulse in the second trial.
The momentum in the first trial is half the impulse in the second trial.
Well, it's quite a baller experiment you've got there, literally. Let's break it down.
First, we need to understand that impulse is the change in momentum of an object, and momentum is the product of an object's mass and velocity.
Now, in the first trial, the balls collide for a shorter duration, 0.01 seconds, while in the second trial, they collide for a longer duration, 0.02 seconds.
Since the amount of force applied to each set of balls is equal, the longer the collision, the greater the impulse. Therefore, we can conclude that the impulse in the second trial is greater than the impulse in the first trial.
So, the statement that stands tall amidst this ball-tastic confusion is: "The impulse in the second trial is twice the impulse in the first trial." And that's a slam-dunk answer, my friend!
To determine the correct statement about these trials, we first need to understand the concepts of momentum and impulse.
Momentum is the product of an object's mass and velocity. It is a vector quantity and is conserved in a closed system, meaning that the total momentum before and after a collision remains the same.
Impulse, on the other hand, is the product of force and the time interval during which the force acts. It is also a vector quantity and is equal to the change in momentum of an object.
Now, let's examine the statements:
Statement 1: The momentum in the first trial is twice the impulse in the second trial.
To determine if this statement is correct, we need to compare the momentum and impulse separately for each trial. The statement does not directly compare momentum and impulse but rather states that the momentum in the first trial is twice the impulse in the second trial. Since momentum and impulse are different quantities, this statement cannot be considered correct.
Statement 2: The impulse in the first trial is half the impulse in the second trial.
To determine if this statement is correct, we can compare the time intervals involved in each trial. Given that the time of collision in the first trial is 0.01 seconds and in the second trial is 0.02 seconds, it follows that the impulse in the first trial is indeed half of the impulse in the second trial. Therefore, this statement is correct.
Statement 3: The impulse in the first trial is twice the impulse in the second trial.
As explained earlier, the impulse in the first trial is half the impulse in the second trial. Hence, this statement is incorrect.
Statement 4: The momentum in the first trial is half the impulse in the second trial.
This statement compares momentum and impulse, but it incorrectly states that the momentum in the first trial is half the impulse in the second trial. Therefore, this statement is incorrect.
In summary, the correct statement about these trials is: The impulse in the first trial is half the impulse in the second trial.
