For example, if two balls of different mass travelling at different speeds strike each other from opposite directions, I know due to conservation of momentum that the total momentum after the collision will be the same, and that both balls will now be moving away from each other, and their masses will be the same- but how do you work what their individual velocites will be? How is the total final momentum distributed between them?

any comparison for how strong this force is? (eg. can be compared to a mallet crushing a concrete block)

i need it for my research paper... thank you

how can our mass increase?
mass always remains a constant.

ok, i know this isn't possible. But let's say, hypothetically, i have a marble that is at absolute zero, and it's sliding across a slab of ice that is absolute zero. would there ever be any friction caused?

Can you please help me with the following problem?
I have four masses connected by massless rigid rods so that they form the square in xy plane (each rod has length 10cm). I need to to find the moment of inertia about an axis that passes through the mass positioned at the lower left vertex of the square and perpendicular to the page. The mass at that point is 100g and all other masses are 200g.
I have a feeling that this should be very simple but all I've got is the center of mass - (5.7cm, 5.7cm) using the coordinate system with the origin at that lower left corner, and (0,10), (10, 0) and (10, 10) as the coordinates of other masses.I have the final solution but I really need the procedure how to get there.
Thanks for any help!

I cannot understand this problem. Please help me :( I would appreciate it a lot. Thank you much.

Piston 1 (in the figure linked) has a diameter of 0.30 in. Piston 2 has a diammeter of 1.5 in. In the absence of friction, determine the force necessary to support the 500 lb weight.

A point source of light illuminates an aperture 2.20 m away. A 14.0 cm-wide bright patch of light appears on a screen 1.40 m behind the aperture.

How wide is the aperture?

Can someone guide me through this problem or at least put me on track. I don't expect you to just give me the answer that wouldn't be learning. Thanks.

I know that sucking in helium changes your pitch which can be really funny, but are there any serious conotations to sucking in helium aside from that (which is not serious at all)?

The cable AB keeps the 8-kg collar A in place on the smooth bar CD. The y axis points upward. Determine the distance s from C to the collar A for which the tension in the cable is 150N.
location of:
B: (0m, 0.5m, 0.15m)
C: (0.4m, 0.3m, 0m)
D: (0.2m, 0m, 0.25m)

collar A's location is unknown. The required is the distance between C and collar A.

Is it possible to plug a power strip into itself? It doesnt neccessarily have to allow something to run off of it, but just so that the light will continue to show? If so, how long would it have to be?
