[AP Physics C: Mechanics] Dimensional analysis of the equation J (impulse) = Ξp (change in momentum)?

I keep getting caught up because when I finish putting them all in their units, I end up with kg(m/s) = kg(m/s^(2)). If p is kg(m/s), wouldn't Ξp have to be kg(m/s^(2))? But I know that Ξp is kg(m/s) and that J = kg(m/s), but I am struggling to prove that the two equal each other.

Physics HL question that im not sure how to do... (Momentum and Impulse question)

A 60.0 kg boy standing on a 5.0 kg skateboard is holding two identical rocks each of mass 3.0 kg. He throws them both in front of himself at the same time with a velocity of 4.0 msβ1 with respect to the skateboard. Determine the final velocity of the boy if friction is ignored.

[College Physics 201] Impulse/Linear Momentum problem

I'm stuck on this problem:

A 3 kg object moving at 4 m/s, overtakes a 2 kg object moving in the same direction at 2 m/s. if they collide elastically, what is the final velocity of each object?

How do I even begin solving it? I missed my last lecture and my professor doesn't record his sessions. Can someone please walk me through it?

[Grade 11 Physics]In this problem the momentum is conserved along the incline because the impulse is perpendicular to it. But then why is it conserved in the horizontal direction but not in the vertical direction? Is it due to the normal reaction on the wedge by the ground?

[GCSE (9-1) Combined Science Physics: Momentum, impulse and law of conservation of momentum] So what with classes being out this isnβt exactly homework but hopefully you guys can still help. I was practicing my physics online when one question seemed to throw me off. Can you help?

Question:

"π΄ and π΅ are travelling together until pushed apart by explosions. 'ππ΄' means 'mass of π΄'."

"( Part D ) What is the mass of π΅ if the initial combined velocity is β4.0m/s, the 9.0kg object π΄ is travelling at β5.0m/s after and π΅ is travelling at +6.0m/s after?"

How far Iβve got:

All I know so far is that momentum measures how much motion an object has, taking into account its mass and velocity. Momentum is a vector and it is calculated using the formula **momentum (kg m/s) = mass (kg) β’ velocity (m/s).

I also know about the law of conservation of momentum, how the initial momentum is equal to the final momentum.

So, (9kg β’ Initial velocity of A (?)) + (mass of B (?) β’ Initial velocity of B (?)) = (9kg β’ -5m/s) + (mass of B (?) β’ +6m/s).

Thatβs as far as I got, any advice?

Add Force or Add Impulse with Physics strength widely varies based on mobile device!

Testing on multiple phone devices, the "jump" strength varies! Some times its barely a jump when you tap your screen, other times when you tap the screen, the jump (add force) shoots you way in the air. It seems to depend on the device. Is there something I need to lock to keep everything smooth?

Jump Functionality. The green line is going to the Event Tick Delta time.
