Question 12

A student carries out an experiment to estimate the acceleration due to gravity, ggg.

She drops a solid plastic sphere from a balcony and measures the time, ttt, it takes to fall to the ground through a height, hhh.

She records the following measurements:

  • Height, h=3.60 mh = 3.60\text{ m}h=3.60 m
  • Time, t=0.86 st = 0.86\text{ s}t=0.86 s

Calculate the value of g g\,g from these measurements.

Use the equation:

g=2ht2 g = \frac{2h}{t^2} g=t22h​
