A 7.50kg block starting at rest slides down a frictionless ramp of height 2.25m at a velocity of 1.50 m/s. it crosses a rough patch that is 2.5m long and exerts a force of 3N. It then continues to the other side of the ramp which is angled at 35 degrees(I dont think this matters b/c it is frictionless). How can I find how many times the block will cross the rough patch? I tried a few equations which didn't make sense....

I am a recent 2009 high school graduate with a gpa of 3.45 and i was looking into colleges in Germany. I really like the University of Bonn and would like to know how to get an Application (in english) and learn about financial aid. My German is not that great but i will hope to speak fluent in a year. Does anyone know where to go to get an application or learn about financial aid...or any other good colleges near Cologne or Frankfurt? Thanks!!

I am taking JACK3D which is a pre workout and also i am taking Anabolic Halo by Muscletech and i have a military drug test next wednesday and i was wondering if these supps would cause you to fail a drug test for military. I already told my recruiter that i was taking this he just told me its fine but research it to see if it could cause it to go wacky on the test. Anyone Know???

I have had a red spot above my lip for about 3 months now it started as a red bump then i popped it and some puss came out. As it faded it left a noticible red spot with a white center. I have tried EVERYTHING to get rid of it and it wont fade. I have used mederma, scar lotion, benzol peroxide, lemon juice, visene, powdered milk with honey, toothpaste, and i have even tried just leaving it alone for a few weeks and NOTHING seems to work!! It is so frustrating...should i go see a Dermatologist or should i keep trying different things, and dont tell me just put make-up over it first off im a guy and secondly that does nothing to get rid of it. Thanks for your help.
