## Homework Statement

I'm trying to find the theoretical time it takes for a glue stick to roll down an inclined plane of 10 degrees. We then have to compare it to the practical value, which was 1.09 secs.(Average over 10 repetitions). The glue stick has a mass of 10g. The distance of the inclined plane was 41 cm.

## Homework Equations

a = g * sin( theta ) for acceleration where theta is 10 degrees.

t = SQRT (2d/a) derived from d = d0 + v0t + (1/2)at2

## The Attempt at a Solution

a = 9.8 * sin(10)

a ≈1.70m/s^2

t = SQRT (2* 41/1.7)

t ≈ 6.95.

6.95 does not equal 1.09 at all, so I'm asking did I use the right formula? If not what are the right formulas. And could someone please provide me with a worked example so I can understand this more clearly.

I'm only a high school student doing this as an independent research project so please don't use advanced language, if you have to can you please explain it as well.

Thank you very much, you help is much appreciated. :D
