Estimate the average force exerted on the person's feet by the ground if the landing is with bent legs. When the legs are bent, assume the body moves about 44 cm during impact. She is 65 kg and jumps from a height of 2.9 m.

THANK YOU!

A 70 kg meteorite buries itself 5.0 m into soft mud. The force between the meteorite and the mud is given by = (660 N/m^3)x^3, where x is the depth in the mud.

What was the speed of the meteorite when it initially impacted the mud?

Thank you so much!!! If you help me, I will choose you as best answer! :D

Does anyone either have or know where I can find Appendix D for Essential Calculus Early Transcendentals?? I need to do 1-7 for hw but my book doesn't have it...!!!

1) lim x-->pi ((e^sinx)-1)/x-pi

2) find y' if x^y=y^x

Please explain! Even if you don't know both, even ONE will help! THANK YOU SO MUCH!

Find constants A, B, and C such that the function y=Ax^2+Bx+C satisfies the differential equation y''+y'-2y=x^2. THANK YOU SO MUCH!

I have been trying to find a website with just a bunch of hair styles and cuts but I can't find anything really good. Can anyone tell me where to find something like that or have any suggestions? My hair is long and red right now. I think I want to go shorter and maybe cut bangs but I am not quite sure because I don't want to look even younger than I already do....

Is there a website to check admission status to SSU? I want to be able to check to see if I got in.

Where can I find Ruby Red Squirt in or near San Francisco/Marin area?? I can't find it anywhere around here!! The closest is in a wierd gas station in Redwood City....which is too far! Help me PLEASE!!! Also, does anyone know where to find Pepsi Holiday Spice? It was discontinued. Thanks!

Where can I watch episodes or clips of The Real World San Diego? I have already tried YouTube.com and there is nothing!! If you have direct links too that would be WONDERFUL!!! Thank you!!!

1. A solution of water and a nonvolatile, nonionizing compound is placed in a tube with a semipermeable membrane on one side. The tube is placed in a beaker of pure water. What initial net effect will occur?

a) water will flow from the beaker to the tube

b) water will flow from the tube to the beaker

c) the compound will pass through the membrane into the solution

d) nothing will move through the membrane either way

e) equilibrium is immediately established

2. When a nonvolatile solute is added to a volatile solvent, the solution vapor pressure ________, the boiling point __________, the freezing point _________, and the osmotic pressure across a semipermeable membrane ___________.

a) decreases, increases, decreases, decreases

b) increases, increases, decreases, decreases

c) increases, decreases, increases, decreases

d) decreases, decreases, increases, decreases

e) decreases, increases, decreases, increases

THANK YOU!!!

1. Explain the following on the basis of the behavior of atoms and /or ions:

a) salt is used on icy roads

b) adding a solute to a solvent extends the liquid phase over a larger temperature range

2. Indicate the type of crystal (molecular, metallic, covalent- network, or ionic) for each of the following

a) gold

b) carbon dioxide

c) lithium flouride

d) krypton

3. Identify types of intermolecular forces that are present in each and identify which of each pair has the higher boiling point:

a) C6H14 and C8H18

b) CH3OH and CH3SH

THANK YOU!!! I am studying for a final and cannot seem to get these! It would help so much! No, this is not my homework, it is a study guide.

A liquid placed in a closed container will evaporate until equilibrium is reached. At equilibrium, which of the statements a through d is not true?

a) The partial pressure exerted by the vapor molecules is called the vapor pressure of the liquid

b) Liquid molecules are still evaporating

c) The number of vapor molecules remains essentially constant

d) The boundary (meniscus) between the liquid and vapor disappears

e) All of these are true

I think it is either d or e.

Which of the following has the highest melting temperature?

a) H2O

b) CO2

c) S8

d) MgF2

e) P4

How many weeks does a high school sports season usually last?

Does anyone have any advice about college applications or applying to Stanford or UC Berkeley specifically? Any specific essay topics or answers?? I'm applying to college and want to do the best I can. Thank you!

Does anyone know if there is a movie out there that would relate to "Franny and Zooey?" I need to watch a movie that relates to the book and write a comparison. ANYTHING would help!

Does anyone have the answers to the AP Calculus Free response questions written out or know where I can find them??? I need to check my answers because I don't think i am doing them right.

Would you date someone seriously and potentially marry a person with a life-threatening condition who could die the next day or could live for years to come if you were in love with him or her? Or would you let yourself get close enough to that person or stay far away because you know you might lost him or her?
