The figure shows a velocity-time graph of a particle moving along a straight line Identify the region in which the rate of change of velocity $\left| {\frac{{\Delta \vec v}}{{\Delta t}}} \right|$ of the particle is maximum
$0$ to $2\,\,s$
$2$ $4\,\,s$
$4$ to $6 \,\,s$
$6$ to $8\,\, s$
A particle is moving with velocity $\vec v = K(y\hat i + x\hat j)$ where $K$ is a constant. The general equation for its path is
Find the value of Relative velocity of any two particles moving in a frame of reference.
and direction of the vectors $\hat{ i }+\hat{ j }$, and $\hat{ i }-\hat{ j }$ ? What are the components of a vector $A =2 \hat{ i }+3 \hat{ j }$ along the directions of $\hat{ i }+\hat{ j }$ and $\hat{ i }-\hat{ j } ?$
