## Homework Statement

I have got a lab on 'braking distance of a wooden block' and I have to find an equation which fits our experiment and find the uncertainty. I have an equation but I can't find the uncertainty.

This is how, I went about my lab...

To find the relationship between the mass of the wooden block and the braking distance, we incrementally increase the mass of the wooden block. With the help of rubber bands, we project the wooden block in a linear motion on a plane surface. Then, we record the braking distance.

## Homework Equations

I have come up with these equations

lg(d)=-0.8814 lg(m)+3.9708

lg(d)=-0.8814 lg(m)+lg(〖10〗^3.9708)

=lg(m^(-0.8814) )+lg(〖10〗^3.9708)

=lg(m^(-0.8814) ) ×(〖10〗^3.9708)

d=9350m^(-0.88)

=9350m^((-88)⁄100)

d^100=〖9350〗^100 m^(-0.88)

How do I find the uncertainity and how do I go about it? It would really helpful if you guys reply quickly, the lab is due tomorrow.
