The figure shows a velocity-time graph of a particle moving along a straight line The correct displacement-time graph of the particle is shown as
The position of a particle moving in the $xy-$plane at any time $t$ is given by $x = (3{t^2} - 6t)$ metres, $y = ({t^2} - 2t)$ metres. Select the correct statement about the moving particle from the following
Let $\vec v$ and $\vec a$ denote the velocity and acceleration respectively of a body in one-dimensional motion
If the position vector of a particle is
$\vec r = - \cos \,t\hat i + \sin \,t\hat j - 18\,t\hat k$
then what is the magnitude of its acceleration ?
A particle has initial velocity $(2\hat i + 3\hat j ) $ and has acceleration $(0.3\,\hat i + 0.2\,\hat j)$ . Its speed after $10\,s$ is
The figure shows the velocity $(v)$ of a particle plotted against time $(t)$
