It depends. If you are driving and the person doesn't look like a serial killer, you should stop.
Answer: Respective answers are 1.27 m/s^2 and 90.17 N
Explanation:
Explanation requires basic knowledge of forces in physics. The solutions are attached in this response. To summarize:
- Newton's Second Law -> F = ma
- Force of friction = Fn (normal force) x µk (coefficient of kinetic friction)
- Because the surface is leveled, Fn = Fg, Fg = mg
- The crates exert the same amount of force on each other because of the rule of action // reaction (Newton's Third Law)

Atoms with unbalanced electrical charges are called ions.
Those with positive charges are called cations.
Those with negative charges are called anions.
The variable represented by that symbol is: d. Net force.
