Question

A body start from rest and then move with uniform acceleration.then

a) it's displacement is directly proportional to the square of the time
b) it's displacement is inversely proportional to the square of the time
c) it may move along a circle
d) it always moves in a straight line

Answer 1

B its displacement is inversely proportional to the square of the time

Answer 2

s = ut + 1/2at²
s = 0(t) + 1/2at²
s = 1/2at²
s is directly proportional to t²
(because here 1/2a is constant)

option a) is correct answer
