______________ Will the soap floatorsink?
For the RipStik Data graph and the lines on that graph:
_____ Which letter labels the RipStik not moving, stationary?
_____ Which letter labels the RipStik moving at a constant speed, no acceleration?
_____ Which letter labels the RipStik moving faster at a constant rate of acceleration?
_____ Which letter labels the RipStik moving with a non-constant deceleration?
_______ ___________ Determine the speed of RipStik run C.
_______ ___________ Determine the speed of RipStik run D.
_______ ___________ Determine the speed of RipStik run B from 0 to 1 second.
_______ ___________ Determine the speed of RipStik run B from 2 to 5 seconds.
_______ ___________ For RipStik run A:
distance = ½*acceleration*time².
The coordinate shown on the graph as a square on line A is at (3 s, 900 cm). Using the equation and the coordinate, calculate the value of the acceleration a.
Short form of the same equation: d=½at²
For the following RipStik velocity data and chart
__________ _____ Given the equation d = 250t + 500, determine the velocity ѵ of the RipStik.
__________ _____ If the RipStik continued at that velocity for 60 seconds, how far would the RipStik go?
__________ _____ If the RipStik continued at that velocity for 5,000 centimeters, how long in seconds would it take the RipStik?
On Monday I rode a RipStik up a gentle slope, turned around, and came back down the slope.
___________________ What is the name of the shape formed by the curve on the graph?
___________________ Between zero and ten seconds, what is happening to my velocity?
___________________ At exactly ten seconds, what is my velocity according to the graph?
___________________ Between ten and twenty seconds, what is happening to my velocity?
___________________ During the twenty second run, is the direction of the force on the RipStik changing?
A bar of Lux Magical Spell soap has a length of 8.0 cm, a width of 5.0 cm, a height of 2.0 cm, and a mass of 90.0 grams.
__________ _____ What is the volume of the soap?
__________ _____ What is the density of the soap?
__________ _____ What will be the slope of the volume (cm³) versus mass (g) line on an xy scattergraph of volume versus mass for the Lux soap?
The data in the table and graphs are from a lab three ball dropping experiment.
_______________ _________ According to the data and graphs, what is the acceleration of gravity?
Volume V = length l × width w × height h
mass m = density ρ × Volume V
d = ѵt
ѵ = at d = ½at² d = ½gt²
where g is the acceleration of gravity. g = 979 cm/s²
