On the basis of which characteristics jute is considerd as a natural fibre​

Jute is obtained from Jute plant naturally that is why it is considered as a Natural Fibre. It seems golden in color.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be

double the distance = divide strength by 4
