A ball starts at the top of a ramp with an incline of 7 degrees and rolls down, picking up speed. (see the table below)

Time (s) Position (m)

(a) Linearize the data and find the slope of the new line. [Slope=.3745?]
(b) Find the acceleration of gravity using the slope of your new line.
(c) Find the theoretical acceleration down a ramp with an incline of 7 degrees. Describe how your value compares and give a possible reason for any difference.
[10m/s/s *sin(7degrees) = 1.21m/s/s?]
