Using the Graphs to Find Equations

Today, we'll take a look at how those graphs we've been using work into the kinematic equations.  It's a process that uses area and slope and replaces the graph model with a formulaic mathematical model.

WS 1-4 must be done at the the beginning of class tomorrow.

Determining your vertical jump rate using the data from Logger Pro.

Yesterday, we all took the time to do a vertical jump.   Your goal is to calculate your rate of deceleration as you went up and the rate of acceleration as you went back down.  

For the jump, use the data points at the bottom of the jump and the top to determine v(f), distance vertical, and elapsed time.   Calculate your v(i) and your acceleration, based on this assumption.   Show work.

For the acceleration rate back down use your v(f) at the top of the jump, the distance vertical, and the elapsed time.   Calculate your v(f) at the instant before you hit the ground, and your acceleration, based on these assumptions.  Show work.
