Question

For my IA, we need to find an experimental value of gravity. I have found the acceleration of a cart on a ramp (0.69m/s^2) - just confused how I find g? (Angle of ramp is 3.3 degrees). Thanks! :-)

Answer 1

\[
g = \frac{F_g}{m}
\]And \[
a = \frac{F_g\sin(\theta)}{m}
\]This means: \[
g\sin(\theta) = a \implies g = a\csc(\theta)
\]
