1. The problem statement, all variables and given/known d Let's say there's a tank filled with a solution to its maximum volume V. Initially, the solution in V is water mixed with some amount of salt S. The objective is to add more of a solution also consisting of water and salt such that the...

I was able to solve the problem guys, thanks for your help

So, I redid my calculations for the eigenvalues and after taking out the factor of 4 i found -1 and 1, do i need to multiply theses values by the factor of 4 that I took out? There is also a hint that says my answer will be a formula that involves n

Homework Statement If n is a positive integer, then 2x2 matrix [-32,252] [-4,32] raised to the power of n is... Homework Equations I know that first I should diagonalize the given matrix, something I also seem to have a hard time with. The Attempt at a Solution I determined the eigenvalues...

Homework Statement Find the matrix that represents a rotation counterclockwise around the origin by 75 degrees followed by a reflection about the x-axis Homework Equations I know that for A rotated counter clockwise you use the 2x2 matirx [cos(theta), -sin(theta)] [sin(theta, cos(theta)] and...

So wouldn't I first need the force applied to find the force of normal and friction forces?

But wouldn't that mean you'd need the force applied to begin with in order to get the force of friction since you need the normal force?

Ok, do I also have to subtract the y component of the force applied rather than just setting the normal force equal to the gravitational force?

Ok, so I was told that my error was that I set the normal force in the second method equal to the y-component of gravity, relative to the table. So, this is as far as I get

This is what my problem is I guess

2 I figured the normal force would be equal to the y-component of gravity, yes.

I believe I am trying to solve for the amount of force necessary to move the sled in each situation.
