A smooth inclined plane is inclined at an angle θ with the horizontal. a body starts from rest and slides down the inclined surface, then the time taken by the body to reach the bottom is:

Answer 1

Hey Spidey ^^ Big Fan !!

Feels so awesome to be able to answer ^^"

'kay !

Force along the incline :

$mg \sin \theta$

Assuming zero Friction :

$accel. = g \sin \theta$

By Laws of motion, and that body starts from rest :

${t}^{2} = \frac{2s}{g \sin \theta }$

And there you get the time taken by the body ^^
