it depends on the weight on the stone, the wind speed at the time, the strength of velocity, etc.
4 Seconds
500/(speed of a roadrunner in meters per second) seconds
It depends how fast u can run
It depends on how fast you walk.
6 hours
THE MOON IS PURPLE
It depends on how much the stone weigh. And how tall the roof is...
9.8 m/s meters per second that is.
4 Seconds
h=vot+(1/2)gt2, vo=0 h=(1/2)gt2 t2=2h/g t=sqrt(2h/g)=sqrt(2x490/9.8)=sqrt(100)=10 seconds
If you get the speed of the rock then you can use Time= distance/ speed So all you need is the speed and you can work it out
You didn't tell us how long it took to walk those 3.33 meters, so it is impossible to know how long 100 meters would take.
As long as your mom took to fall for me.
In
15 m divided by 2.5 m s-1 is 6 s.
D = 1/2 G T2T = sqrt(2D/G) = sqrt(352.8/9.8)= 6 seconds
