I already found the magnitude of the acceleration, but I can't figure out how to calculate the coefficient of kinetic friction for the incline.
I've looked at other questions/answers, none have helped me get the right answer on this one.

During a tennis serve, a racket is given an angular acceleration of magnitude 125 rad/s2. At the top of the serve, the racket has an angular speed of 13 rad/s. If the distance between the top of the racket and the shoulder is 1.0 m, find the magnitude of the total acceleration of the top of the racket.

For a 1D integral over a symmetric interval we have
Int(f(x),x = -a..a) = Int(f(x),x = -a..0) + Int(f(x),x = 0..a)
Now break up the double integral similarly:
Int(Int(f(x,y),x = -a..a),y = -a..a)
The first one to get the correct expansion get 10 points.

Let's say I built a time machine and travelled back in time to, lets say 10 years before I was born. I find my mother and kill her. Is this possible? I believe it isn't. That would mean she never gave birth to me. Therefore, how could I kill her? In fact, how could I exist at all to have built a time machine?

Which probably will never happen, but think with me for a second...

What would a clear night look like?

Would half of the sky be Saturn's ring just stretching for miles? It would be a beautiful sight if so. Possibly the most beautiful sight that I can imagine at least.

And also, Mars... When we do put humans there... Does anyone know if there are plans to set up a telescope there? Would it be possible to get a clearer view of Pluto, and possibly even discover other celestial bodies that we cannot see from Earth?
