A 40-kg box is moving on the floor. The coefficient of static friction between the box and the floor is

0.650, and the coefficient of kinetic friction is 0.500. If the pulling force is applied horizontally, what is

the magnitude of the force to maintain a constant velocity motion?

I recently ran over something (possibly a rock) that has caused a very small hole on my 2004 chevy cavalier oil pan. There is a very small leak of oil and I wouldn't want to go through the trouble of buying a whole new oil pan for a teeny tiny hole. Would buying a metal putty, epoxy, be ideal for fixing this problem? If so what kind? If not then please let me know. Oil pan is Aluminum by the way. And of course I know to drain the remaining oil before working on the car.

My girlfriend broke up with me a month ago and it's slowly taking a toll on me mentally. I would do anything to get her back. Anyways has anyone successfully hooked back up with their ex and how long did it take you to do so and how happy are y'all now? Bonus: Do you think writing a letter to my ex explaining how I realized my mistakes in the relationship and how much she means to me could help me get her back? her reason for breaking up with me was because she didnt feel the same anymore after two years of being in a relationship . If not any advice you can give me? Thanks

A hockey player hits a puck giving it an initial velocity. The puck stops when it has traveled 20 meters. Along the way the puck was acted upon a friction coefficient of .2. What is the initial velocity? The question does not give a mass for the puck which isn't necessary for this problem. And my professor likes us to use the force as gravity as g=10m/s^2 (he likes rounding numbers).

A block with mass of 2kg slides UP a frictional incline of 36.9 degrees. The frictional force is 3N. What is the acceleration of the block.

Note: The problem does not state that there is a force pushing the block. The problem is just as stated above. Please help!!!

Please find the derivative using the Chain Rule

I am planning a trip to go to Houston (only an hour from where I live) to attend Coffee and Cars. Every time I click the link for the parking map on where to park a 404 error shows up. So my question is where do I park if I want to attend Coffee and Cars Houston which is held at Vintage Park in North Houston? And also, how much is it to attend the actual event or is it free? Thank you

the function is f(x)=2x^2

and the line is 6x-y+5=0

The question is:

Verify that the intermediate value theorem applies and show that somewhere in the interval [1,2] there is a root of h(x) = -15x^3 +6e^x. Note that you are not being asked to find the root, only to show that one exists.

Please help answer and explain if possible. Thanks

I understand how IVT works, I'm just not good with exponential problems. Please, if possible help me understand what to do with "e" after working this problem. Thanks

It is for a 2003 mustang v6. The socket or bolt oil plug I have now is rounded so I can't take it off as easy. But after I do manage to take it off I want to put the new replacement plug. Where can I buy one? Please help and thanks in advance.

I have received a cateye 49cc pocket bike that has been sitting in a garage for three years from my neighbor. What can I do to check and clean the engine or do I even need to clean it? I just want it to look good as new. Also the engine does run well and have ridden it a couple of times already with no problem. Just want it clean lol

My neighbor gave me his pocket bike that sat in his garage for three years. Of course it has collected lots of dust and dirt. I cleaned the outside body but not the engine or any of the mechanical parts. The bike runs but not as fast as I remembered. I use a 50:1 oil gas ratio. Should I have cleaned the engine? Or what could I do to make it run like new? Also the engine is 49cc.
