1. For the Desmos graph and regression, determine the acceleration of the RipStik from a Monday run. Times are in seconds, distances in centimeters.
   
   
   acceleration: __________ __________
2. __________ __________ If the RipStik continued to accelerate at the rate above, how far will the RipStik travel in 30 seconds?
3. For the Desmos graph and regression, determine the acceleration and initial velocity of the RipStik from a Wednesday run. Times are in seconds, distances in centimeters.
   
   
   acceleration: __________ __________
   
   initial velocity: __________ __________
4. For the Desmos graph and regression, determine the acceleration of gravity from a Thursday laboratory. Times are in seconds, distances in centimeters.
   
   
   acceleration of gravity: __________ __________
5. __________ __________ What is the raw error with respect to the published value of 980 cm/s²?
6. ________________ What is the percent error?
7. ______________________ How good is the agreement of the experimental value to the published value?
8. __________ __________ If the ball continued to fall and accelerate at the rate above, how far will the ball travel in 30 seconds?

$\mathrm{acceleration}=\frac{\Delta ѵ}{\Delta t}$
ѵ = at
ѵ = gt
d = ½at²
d = ½gt²
where g is the acceleration of gravity
g = 980 cm/s²
