Exploring physics of Distracted Driving #e, f

Does anyone understand how to do this? Are we using the triangle that we predicted? Thanks

I am pretty sure that you use the triangle sketch in B. And then you fill in what the area of a triangle is. Which I believe is the distance the ruler falls but it could be different. You also fill in the formula for finding the area of a triangle. And I think the base of the triangle is your reaction time.

Reid is right and the height of the triangle is the velocity. The formula for area in this problem is A= 1/2 times change in v times change in t.

ok thanks. but how do we plot this on the graph in B?The only info I have is the distance on the ruler, so where do i go from there?

This is great work!!
Sam and Reid are right. The sketch you are making in B is just a sketch, and it's only to help you visualize how you can write an expression for the displacement (represented by the area) of the ruler. Ultimately, you are trying to find a formula for the reaction time, in terms of how far the ruler fell. We will work on this more in class tomorrow.
