Question

Starting from rest, a body takes 4s4s in slipping from top to bottom of an inclined plane. The time taken by the same body in covering one-quarter distance on the same plane from rest will be

Answer 1

HEY DEAR ...

S = u t + 1/2 a t²

a = g Sin Ф,  where Ф = angle of the inclined plane   
u = 0

Hence, s is directly proportional to t².         If distance is 1/4 th  then time taken will be 1/2.

  So  half of 4 secs  is 2 seconds.
