Physics - Kinematics Question with Solution | TestHub

A. Acceleration$=\mathrm{ }$constant;$\mathrm{a}\mathrm{ }\mathrm{v}\to \mathrm{t}$graph will be constant line parallel to time axis. Option$\left(\mathrm{A}\right)$is correct.
B.$\mathrm{v}=\mathrm{u}+\mathrm{a}\mathrm{t}$; velocity vs time graph will be straight line passing through origin. Option$\left(\mathrm{B}\right)$is correct.
$\mathrm{u}=0;\mathrm{ }$initially at rest
$\mathrm{v}=$at
C.$\mathrm{X}=\frac{1}{2}\mathrm{a}{\mathrm{t}}^2$(particle was initially at origin)$\mathrm{v}\to \mathrm{t}$graph will be parabola passing through origin. Option$\left(\mathrm{D}\right)$is correct.
