So we’ve modeled free fall from a couple of different perspectives: knowing ∆y, t, final velocity, but we’ve always done Earth based problems. What about “g”?

Given a list of tools: bowling ball, tall tower (1000 m), radar speed detector, and a tape measure: students were asked to propose a procedure to find “g”. Once the procedure was approved, I gave them an incomplete set of “data” to work with to calculate “g”
