ok, i have to go do laundry now. i hope this game gets played again the next time I'm on, i totally enjoyed that :approve:

oh, i meant is the word: "obsolete", but i guess that's not it ;-)

and is asking for guidance in solving 3 problems really so excessive?

i'm sorry if it appears that way to you, but no, i am not just plugging and chugging. this is all material that i learned a long time ago, and now must remember the formulas to. the textbook i am using is not exactly integrated with the online questions that i am answering. and thus, i am...

is it obsolete?

i still don't quite get how i am to plug this into a formula. i'm assuming that the wording means that the car starts out at 80km/h, displaces 56.7m, then the velocity changes to 47.8km/h and the car moves another 24.4m? if this is so, does reaction time mean the time it takes to change...

i just got that one, but here is another: To stop a car, you require first a certain reaction time to begin braking. Then the car slows under the constant braking deceleration. Suppose that the total distance moved by your car during these two phases is 56.7 m when its initial speed is 80.0...

I have another question: How do I go about this one: A drowsy cat spots a flowerpot that sails first up and then down past an open window. The pot was in view for a total of 0.35 s, and the top-to-bottom height of the window is 2.10 m. How high above the window top did the flowerpot go? I...

vf^2=vi^2+2ad you are awesome

x = x0 + v0t + (1/2)at2 ?

and what do i do about the fact that time isn't specified in the question?

So, to find braking distance for each train in this problem: Two trains, one traveling at 72 km/h and the other at 133 km/h, are headed toward one another along a straight, level track. When they are 860 m apart, each engineer sees the other's train and applies the brakes. The brakes decelerate...

With motion problems, what formula do i use for deceleration of a particle if I am given v and a, and need to find distance?

I guess my brain is fried, I can't figure out what formula to use for this problem: Two trains, one traveling at 72 km/h and the other at 133 km/h, are headed toward one another along a straight, level track. When they are 860 m apart, each engineer sees the other's train and applies the...
