2.Motion in Straight Line
easy
If $x \propto {t^{5/2}}$ , then
A
$v \propto {t^{3/2}}$
B
$a \propto \sqrt t $
C
both$ (A)$ and $(B)$
D
$v \propto \sqrt t $
Solution
Given $x \propto t^2 \quad \Rightarrow x= Kt ^2 \quad$ where $K = constant$
$\therefore$ Velocity of the particle $v =\frac{ dx }{ dt }=2 Kt$
$\therefore$ Acceleration of the particle $a =\frac{ dv }{ dt }=2 K = constant$
