hiker stands on the edge of a cliff 490 above all the ground and drop

1.	hiker stands on the edge of a cliff 490 above all the ground and drop stone . find the time taken by stone to reach the ground and hits the ground. (g=98ms square)
Answer» h=490m u=0m/s g=9.8m/s^2 h=ut+1/2gt^2 490=0+1/29.8t^2 t^2=490/4.9=100 t=10 so REQUIRED TIME is 10 SECONDS.

Answer»

h=490m

u=0m/s

g=9.8m/s^2

h=ut+1/2gt^2

490=0+1/2*9.8*t^2

t^2=490/4.9=100

t=10

so REQUIRED TIME is 10 SECONDS.
