Well, thanks a lot for the help. You, sir, are a life-saver.

Grrr, I'm certainly getting in my "stupid stuff" quota for the day... (a+(b-c))(a-(b-c))?

Wow, now I feel like a moron. Thanks for the help, lol. So, a^2-(b-c)(b-c)... Is that as far as it'll go, or am I missing something again?

[SOLVED] Factoring problem Homework Statement Factorize the following: a^2 - b^2 + 2bc - c^2 The attempt at a solution I know this should be a fairly simple problem, but my brain must be fried or something, I can't seem to come up with anything... There are no factors common to all terms, and...

Hmm... I have no idea what I was thinking when I put 25... Well, thanks a ton for the help, I really appreciate it. Just to make sure... The 2 equations, in their correct forms, are: 112 = 3v1'2 + v2'2 and 40 = 6v1' + 2v2' Then, with those, I can solve for the correct velocities, right...

But with that equation, would I just do what I was doing before, solve for one and plug it into the other equation? Also, does that work when the objects are going in the same direction?

Alright... M1 = 6 V1 = 6 M2 = 2 V2 = 2 Plugging those into the conservation of kinetic energy equation (the one I listed above) I got: 25 = 3v1'2 + v2'2 Plugging them into the conservation of momentum equation: 40 = 6v1' + 2v2' Here's where I'm stuck... If I solve for one variable...

Homework Statement A 6.0 kg cart moving at 6.0 m/s collides with a 2.0 kg cart moving at 2.0 m/s in the same direction on the same track. The collision is cushioned by a perfectly elastic bumper attached to one of the carts. What are the velocities of the carts after the collision? What was...

Homework Statement A glass of water with a mass of 500 g is being pushed horizontally at thetop across a table. The base is 1.5 cm in diameter and i is 5.0 cm tall. The coefficient of static friction is 0.20. Will it slip or tip? Homework Equations Not entirely sure.The Attempt at a...
