what is the observation when bag is drop into the height 40ft.88cm to the ground...?
Answers
: The formula for the time of free fall is:
t=(√2⋅hg)
where:
t is the time duration of a free fall
h is the height of the free fall
g is the acceleration due to gravity

A bit of Newtonian mechanics here:
v = g * t (v=velocity, t = time, g is gravity constant 9,82 m/s^2 on Earth)
Integrated for distance travelled:
h = 1/2 * g * t^2
Lets isolate t:
t^2 = 2h/g
t = sqrt (2h/g)
Lets insert your values:
t = sqrt (2 * 200m / 9,82 m/s^2) = 6,38 seconds
