Question 72: Motion in 1D

Question

A particle starts from origin O from rest and
moves with a uniform acceleration along the
positive x-axis. Identify all figures that
correctly represent the motion qualitatively.
(a = acceleration, v = velocity,
x = displacement, t = time)

Accepted Answer

Given initial velocity u = 0 and acceleration
is constant
At time t
v = 0 + at
$$ \Rightarrow $$ v = at
Also $$x = 0(t) + {1 \over 2}a{t^2}$$
$$ \Rightarrow $$ x = $${1 \over 2}a{t^2}$$
