Hello everyone. I'm trying to find a fiction novel that deals with historical issues in a particular region, e.g. Memoirs of a Geisha (Japan), The Kite Runner (Pakistan). The only problem is that in this search, I cannot use any novel that I have read. The dilemma: how can I know whether the...

Hello everyone. My graphing calculator recently died on me, and I need it over Easter weekend to finish up some work. Is there any applet online or free program that I can use to temporarily replace the TI-83? I need it to be able to perform quadratic regression from plotted points. Thanks...

Having missed most of this material, I am finding myself at odds wih the last question of a homework assignment: A bullet of mass 4.0 g moving horizontally with a velocity of 500 m/s strikes a wooden block, initially at rest, on a rough wooden surface. The bullet passes through the block in a...

Uh...the problem states that this should be taken as a perfectly elastic, linear collision.

Using the conservation of energy formula in the next part of the problem gave me an inequality. Was I supposed to use the full formula or simply calculate the kinetic energy separately? 0.0288 W = 0.0192 W ?

What I'm looking for is a formula to calculate velocity of two objects at minimum separation. I was told that this was the point at which the objects functioned as a single entity, thereby having the same velocity. Will Nydux's formula work for this?

Due to having an extremely trying week recently, I missed a large portion of the conservation of momentum/energy material. So far, I've been relearning and applying with no problems, but now I've hit a roadblock: "Sticky" collisions. A problem on my assignment requires that I use a sticky...

Yes, but the problem doesn't state that the object is at rest, so can we just automatically assume that it is?

Here's the problem. A force F gives an acceleration to an object of a given mass. a) If this mass is doubled and five times the force is applied, what is the current acceleration of the object. b) How will this change the distance covered by this object over a given interval of time...

Thanks! That helps a lot!

Actually, I figured out that rate = velocity. But could you explain the "Flip Simplify" step? It just threw me completely how you arrived at that.

Where did rate come in?

I don't understand this lst part. Should it be t2 = d/2v?

This has been a great help to me, but I'm confused on one point: In t2 = d/2t2, where did 2t2 come from?

Unknowns: Time (any), distance/displacement (any) Known: No acceleration, 48 km/h velocity over half the total distance, average velocity of 90 km/h. Yes, the "first half of the trip" meant by distance. My problem is that I can't just set an appropriate time/ditance and substitute it into...
