box and the floor? If the same box is put on a metal ramp adjusted to an incline of 34 degrees so that when given a tap,the box slides down the ramp at a constant speed,what is the coefficient of friction with the ramp?

40 newtons/300 newtons=a coefficient of friction of 0.133. The ramp question? The COF is tan 34 degrees, which is 0.59.

if you're a rocket scientist or ought to handle this form of aspect on a regularly happening foundation...and that i visit't imagine a unmarried job the position it is going to, why problem about such issues? i'm positive it really is for college/college, yet would not the e book clarify a thanks to make certain this out? There must be some form of mathmatical equation defined previously in the e book. i'm no longer sturdy at math, even with the undeniable fact that it sort of feels to me there are too many variables for the appropriate answer. Inertia has alot to do with it, so does this form of fabrics the field is sliding on. if the metallic is lubricated it is going to bypass a lot swifter lower than universal gravity as compared to the metallic incline being frustrating. Gravity is the basically consistent on your equation. also diverse elements would have diverse friction transformations, i do not see how this will be spoke back with the innovations given, yet back i'm no longer a math buff. individual below me is popular with math :D

30kg applies 30 * 9.8 newtons of force to the floor. This is approximately 300N. It takes 40N to pull the box, so the coeff of friction is 40/300 or about 0.13
For the second problem, find the component of the weight of the box that is normal to the ramp, and the component of the force that is parallel to the ramp. The parallel force must overcome the normal force times the coeff of friction. This should enable you to figure it out.

The co-efficient is a resounding 'what the hell?' Anyway, that is not enough info. Is the box waxed? What metal is the ramp made from? How much force is behind this 'tap'? Come on, I guarantee that if you give me all this extra data, I will answer this.Or I will go hide in the yard.

this is a simple problem no one should answer this. WE WILL NEVER HAVE ANY MORE EDUCATED PEOPLE OF EVERYONE GETS THEIR HOMEWORK DONE ON Y!As.
Please form a study group and put a little sweat into this problem you will be a better person for it. dont you know how to use a book
DONT HELP
