Answer:

you need the speed and the time it took in order to find the acceleration and you can find the acceleration by using this equation: A= S ÷ T where a is acceleration, s is speed and t is time.

Measurements are needed to measure the acceleration of free fall of a body from rest is the height and time of fall.

let us assume,

  • the body is falls from some height (h)
  • the Initial velocity would be

              u = 0

  • The distance (h) is traveled by the body in the vertical direction with constant acceleration.
  • the total time is taken by the body would be = t

Acceleration is constant so, the equation of motion in the perpendicular direction can be applied.

That is,

[tex]y = ut + (1/2) at^2[/tex]

in this case,

y = h  and a = acceleration of free fall

Solution:

Putting values in the equation:

[tex]h = 0 + (1/2) at^2\\t^2 = 2h/a \\a= 2h/t^2[/tex]

The correct answer would be the height and time of fall.
