Inelastic Collision of an object Problem

AI Thread Summary
In a perfectly inelastic collision, a 1.5 kg object moving at 14 m/s collides with a stationary 2.0 kg object, requiring the calculation of the combined system's velocity before ascending an incline. The discussion emphasizes using conservation of momentum to determine this velocity, followed by analyzing forces acting on the system to find the distance traveled up the slope. Participants mention the need to equate kinetic energy to potential energy to solve for height, then apply trigonometry to find the distance moved. One user confirms they solved the problem with the help of others in the thread. The conversation highlights collaborative problem-solving in physics related to inelastic collisions and motion on an incline.

A m=1.5 kg object moving at 14 m/s collides with a stationary 2.0 kg object. If the collision is perfectly inelastic, how far along the inclined plane will the combined system travel? Neglect Friction.

Any help would be appreciated

This is a three part question. First you need to calculate the velocity of the combined mass system before it begins up the incline. Second, you need to determine what will slow the combined mass system down, and to what magnitude (free-body diagram). Then, it's simple kinematics to see how far up the slope the system will go.
 
I have the same exact problem with the incline...I think we have the same prof. Is it from the study guide on webassign?
 
Using conservation momentum find the velocity of the combined mass before it starts climbing the inclined plane. After moving certain distance along inclined plane combined blocks stop. So loss of KE = gain in PE. From this you can get the height of the combind blocks from the ground. Using the angle of inclination you can find the distance moved by the blocks.

yea its a group problem on webassign for my class

edit: I figured it out, thanks for the the help. find the KE (1/2mv^2) then set it equal to PE (mgh) and solve for h. then use trig to find the distance traveled. Again, thanks for the help, and there's one other problem ill be posting in a bit.

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
Thread 'Voltmeter readings for this circuit with switches'
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 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
