Question

A student investigates skateboarding down a slope. She times how long it takes her to skateboard between two lines on a sloping pavement. She varies the distance between the two lines and records her results in a table.
Distance s/m time t/s
2 2.32
4 4.23
9 8.22
11 9.53

The student read that the equation which might relate to the motion of the skateboard is

X = Ut + ½ at2


(a) What conclusions do you draw from the results above.
(b) What factors influences the results.
