In free fall, a body of mass 1kg drops from a height of 125m from rest in 5s. How long will it take another body of mass 2kg to fall from rest from the same height? [g = 10ms^-1·]

h=1/2gt²
h=125m
t=?
g=10m/s²

125= 1/2×10t²
125=5t²
t²=125/5
t²=25
therefore
t=√25
t=5sec.


which is true. at free fall all object will reach the ground at the same time

Neglecting air resistance all body falls freely under gravity at the same speed and time interval

True under free fall, objects land on the ground at the same time neglecting air resistance.
