I need some help with Physics. I've had this one question I haven't been able to solve for some time and I need some help on it ><; A 40.0 kg crate is lying on the floor. Two people pull on the crate. One pulls with 200.0 N in the East direction while the other pulls with 180.0 N in 30 degrees East of North [N30E]. If the coefficient of kinetic friction between the crate and the floor is 0.15, determine: A) How long does it take them to move the crate from 12.0m if it starts from rest? B) The direction the crate moves in

Tricky math problem! D: Okay, I've been trying to work this one problem for about an hour with 4 other friends at school and it seems none of us can come up with an answer.. Here it is: At one time, the number of employees in a company was a perfect square. Later, with an increase of 100 employees, the number of employees was one more than a perfect square. Now with an additional increase of 100 employees, the total number is again a perfect square. The original number of employees was a multiple of.. A) 5 B) 7 C) 9 D) 11 E) 13 If you know how to solve this, could you explain this mathematically? x.x Thanks~ It is appreciated

Hackshield error 0x000000(1) ever since V0.91 I've had this problem ever since the v0.91 patch and it still isn't fixed >< I log in the website and start the game like usual and Hackshield starts loading up like it's supposed to. But after it finishes loading, [url=http://img46.imageshack.us/img46/6344/72116282.png]the Maplestory game launcher pops up[/url]. When I click the Start button, it loads Hackshield [b]again[/b] [url=http://img98.imageshack.us/img98/7916/19475893.png]and gives me the 0x000000(1) error[/url]. I click the OK button on the error and [url=http://img23.imageshack.us/img23/5167/92134122.png]two more screens pop up[/url]. Does anybody know how to fix this error? I've tried literally everything.

Physics homework help. Okay, I'm having a bit of a problem with some grade 11 Physics homework and I need some help.. A 5.0 kg object is at rest on a horizontal surface. The coefficient of static friction between the object and the surface is 0.50µs and the coefficient of kinetic friction is 0.40µk. A person pushes to the left on an object with a gradually increasing horizontal applied force. Describe what will happen to the acceleration and net force as the horizontal applied force increases by identifying both the direction and magnitude. (Explain your reasoning) A 10kg mass is held against a wall with a force of 220N. a) Find the minimum coefficient of the static friction. (I found this out already. It is 0.45µs.) b) Find two ways of
