D) To overcome the electrostatic forces between opposing nuclei.
Answer:
So, if the car slips in mud it will either skid or slide depending on the size of the mud puddle.
Does this work?
X=v(initial)t+.5(a)t^2. Car B's displacement can be represented by equation x=45t. Car A can be represented by the equation x=.5(5)t^2. Plug these equations into a graphing calc and find intercept, the x value is time, the y is displacement.
