The most frustrating part is that I apparently was correct the first time, but the answer they wanted was positive rather than negative. But looking at the problem, the vector is clearly negative in the X and Y directions!
Think of mu (μ) as the magnitude of how much an object cancels out the forces trying to accelerate it.
There are two mu values for any object. The static and kinetic friction coefficients. Static is the resistance for an object to acceleration, kinetic is the resistance to acceleration after...
I want to apologize ahead of time for my apparent inability to get LaTeX to display properly.

λ = 3.8 x 10^(-6) C/m
R = 32m
r = magnitude of the hypotenuse (the book's convention, a poor choice IMHO)
r = \sqrt{R^2 + x^2}
k = 8.988 x 10^9

cosθ = x/r

Your acceleration is your change in velocity over time. So if you started at v0 = 5 m/s and accelerated to v= 6 m/s you would have acceleration. If you constantly move 5 m/s, you have acceleration = 0.
So if we plugged this into the equation,
Force = mass (0)
If you have zero...
Homework Statement
In the figure, you throw a ball toward a wall at speed 26.0 m/s and at angle θ0 = 37.0˚ above the horizontal. The wall is distance d = 17.0 m from the release point of the ball. (a) How far above the release point does the ball hit the wall? What are the (b) horizontal and...
