How Does a Force Impact Final Velocity in One-Dimensional Collisions?

AI Thread Summary
In a one-dimensional collision scenario, an object with a mass of 2.5 kg moves at a velocity of -1.0 m/s and experiences a force of 4 N for 3 seconds. The impulse experienced by the object is calculated, leading to the equation 12 = 2.5(v + 1). This equation can be solved to find the final velocity after the force is applied. The discussion emphasizes the importance of understanding impulse and its effect on final velocity in collision problems. The final velocity can be determined by rearranging the equation and solving for v.

Homework Statement


An object of mass 2.5kg is moving in the negative x direction at a velocity of 1.0
m/s. It experiences a force shown of 4N for 3 seconds, what is the final velocity after the object has experienced the impulse.

Homework Equations





The Attempt at a Solution


2.5(v-(-1)=12N
And after that I am not quite sure if that is correct or how to fully solve.

It's correct so far. Now recall from maths that a-(-b) = a+b, so 12=2.5\times(v+1) and hopefully you should be able to solve for v from there :)
 
Thank you. It is much appreciated.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
