Ignore relativistic effects, assume that the coefficient of friction between the dominoes and the floor is excessively large, and assume the naturally occuring variables, such as sound and heat loss, do not apply.

**PART 1**

If you were to graph the topple rate (dominoes toppled over a second) over time, what would the basic shape of the line be?

**PART 2**

What are all the necessary variables in determining the equation of the line?

**PART 3**

Use the variables from the previous part to create an equation that solves for the topple rate after a certain time has passed.
