A man moves in $x-y$ plane along the path shown. At what point is his average velocity vector in the same direction as his instantaneous velocity vector. The man starts from point $P$.

$A$

$B$

$C$

$D$

Solution

The average velocity will be zero for the region below the line.

Now, The average velocity of the region from point $P$ till the line will be nullified by the vertical component of velocity of region $BCD.$

Thus, the average velocity will only be in the right direction. Thus, direction of average velocity will be same as instantaneous velocity of point $\mathrm{C}$.

The initial velocity of a projectile is $\vec u = (4\hat i + 3\hat j)\,m/s$ it is moving with uniform acceleration $\vec a = (0.4\hat i + 0.3\hat j)\, m/s^2$ The magnitude of its velocity after $10\,s$ is………$m/s$

If vectors $\overrightarrow {A} = cos\omega t\hat i + sin\omega t\hat j$ and $\overrightarrow {B} = cos\frac{{\omega t}}{2}\hat i + sin\frac{{\omega t}}{2}\hat j$ are functions of time, then the value of $t$ at which they are orthogonal to each other is
