What time are you using for your inhalations?

I think this is what you're asking: 58 m/s is to 1 m/s as x(her walk speed) is to 1.389 m/s. so her walking speed is just 1.389*58 m/s.

The face of your body, with your arms and such, is less aerodynamic than your back is. So, yes, I would imagine it would slow you down overall.

The block will stop all of the force applied by the bullet; when it just enters the block, the force is equal to that of the force of the bullet, when it stops there is no force. So the average force would be the average of those two forces.

After taking a short break, I figured it out, and it was massively simple. I'll post the answer here so that anyone else Googling in the future can find it. K=1.1 U=-1.3 and K+U = -0.2 since they are inversely proportional, their sum must equal the vibration state.

Homework Statement The figure shows a potential energy curve for the interaction of two neutral atoms. The two-atom system is in a vibrational state indicated by the heavy solid horizontal line. (a) At r = r1, what are the approximate values of the kinetic energy K, the potential energy U...

Tension is equal to mass time acceleration(g in the first equation). So: T=(5m/s/s)(5Kg) = 25N Tension is a force; you could use the other eq just the same.

To find the unit vector you're going to have to divide each component of the vector by the magnitude of the vector.
