I'm studying for a general physics quiz and am having a hard time figuring out how to derive the equations to use for this problem. Don't need it solved, just need some guidance on where to start. Thanks in advance.

A skier slides horizontally along the snow for a distance of 29 m before coming to rest. The coefficient of kinetic friction between the skier and the snow is µk = 0.030. Initially, how fast was the skier going?

I just need to get started, also where ill end up would be nice. I have no idea where to start.

This is the problem:
"Every angle inscribed in a semicircle is a right angle."
Prove this statement using vector method

Im thinking that the cross product will show here because of the right angle part. Just no idea how to get rolling on this, Help would be appreciated. thanks.

This is not an argument thread. I will not reply to any debate or arguments against evolution. This is a list thread only, please.

I'm going to write a comprehensive essay for the sole purpose to prove to my family members who don't believe in evolution that it's true.

I already know a crap load about evolution, but I'd like people to list everything they can think of that is proof of evolution. I probably already know most of it but the purpose of this is so I don't miss anything.

I'll start out:

Vestigial structures: we have structures that serve no purpose but are just remnants of ancestors who did use it. For example, the tailbone.

An A-Shapped Ladder, both sides of the ladder are equal in length. The ladder is standing on a frictionless horixontal surgace, and only the crossbar )which has a negligible mass) of the "A" keeps the ladder from collapsing. The ladder is uniform and has a mass of 20.0 kg. The angle the ladder makes is 30.0 degrees. The length of the ladder if 4.00 m.
