The distance is 80 metres
The speed of gravitational force is 10m/s^2
so,
Time=Distance÷Speed
Time=80÷10
Time=8 seconds
The speed of gravitational force is 10m/s^2
so,
Time=Distance÷Speed
Time=80÷10
Time=8 seconds

if you will put g=10m/s^2 the time of decent will be 4s
tell solution
8 seconds
s=80m,u=0,g=10m/s^2, by 2nd equation of motion s=ut+1/2gt^2 by put the value of each , you can calculate the value of t
thanks
we're welcome
