Answer:
20 mph
Explanation:
Granny stopped from 50mph,
Her deceleration per unit time is
a = 50 - 0 = 50m/hr^2
This is also the amount of deceleration you experience per unit time (because both cars are identical), therefore your final speed with which you collide with the truck will be,
50 = 70 - v
V = 70 - 50 = 20mph

Ions are particles formed when an atom of an element looses or gains electrons to attain a stable configuration.They are either positively charged (cations) or negatively charged (anions). Ionic crystals consists of ions bound together by electrostatic attraction forming a regular arrangement, geometric structure called crystal lattice. In an ionic solid the ions are held by strong attractive forces (tightly bound) and cannot move from their positions in the crystal structure and therefore, do not conduct electricity.
I think it's something like electrons don't attract, cuz you know the saying "Opposites attract." Cause electrons are negative... Ahaha... sorry, I don't know the answer.
