Question

Starting from the rest at the top of the incline plane a body reaches the bottom of the inclined plane in 4 second in what time does the body power one for the distance starting from rest at top

Answer 1

Answer:

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.
