    How do I integrate 2/(1+x^4) to find the area between two curves?

    Find the Area between the two functions. http://www4a.wolframalpha.com/Calculate/MSP/MSP16151chba72gif4040fg0000686h2hea7f943994?MSPStoreType=image/gif&s=54&w=381.&h=306.&cdf=Coordinates&cdf=Tooltips I know the bounds are from x=[-1,1] which gives me the equation... ∫ 2/(1+x4) - x2 dx I...

    How far up the ladder can you climb before it begins to slip?

    can you elaborate on that? I was simply plugging in the equation for Friction at that point. Why is Ff ≤ μN?

    How far up the ladder can you climb before it begins to slip?

    A uniform ladder of length 9 m leans against a frictionless vertical wall making an angle of 47° with the ground. The coefficient of static friction between the ladder and the ground is 0.41. If your mass is 74 kg and the ladder's mass is 33 kg, how far up the ladder can you climb before it...

    Solution to Force & Friction: Find Time for 4kg Block to Drop 7m

    I just copied and pasted this problem out of my homework. That T was already marked. Is there an equation which can relate tension to the solution here?

    Solution to Force & Friction: Find Time for 4kg Block to Drop 7m

    ok I solved the problem. My original equation was wrong. Apparently since both masses are moving with the same acceleration in this system, and there are only so many Newtons to go around, the equation used to find the acceleration looks more like the following: Fsystem = (mB+mA) * a = FA - Ff

    Solution to Force & Friction: Find Time for 4kg Block to Drop 7m

    1. A 5 kg block rests on a horizontal table, attached to a 4 kg block by a light string as shown in the figure. The acceleration of gravity is 9.81 m/s 2 . The coefficient of kinetic friction between the block and the table is 0.3, find the time it takes for the 4 kg mass to fall 7 m to the...
