A particle of mass $m$ is projected at $45^o$ at $V_0$ speed from point $P$ at $t = 0$. The angular momnetum of particle about $P$ at $t = \frac{V_0}{g}$ is:-
$\frac{1}{2 \sqrt 2} \frac{mV_0^3}{g}$
$\frac{1}{2 \sqrt 2} \frac{mV_0^2}{g}$
$\frac{1}{2} \frac{mV_0^3}{g}$
$\frac{1}{2} \frac{mV_0^2}{g}$
A particle is moving along a straight line with increasing speed. Its angular momentum about a fixed point on this line ............
Explain Cartesian components of angular momentum of a particle.
A ball of mass $1 \,kg$ is projected with a velocity of $20 \sqrt{2}\,m / s$ from the origin of an $x y$ co-ordinate axis system at an angle $45^{\circ}$ with $x$-axis (horizontal). The angular momentum [In $SI$ units] of the ball about the point of projection after $2 \,s$ of projection is [take $g=10 \,m / s ^2$ ] ( $y$-axis is taken as vertical)
