A particle moves with constant speed $v$ along a regular hexagon $ABCDEF$ in the same order. Then the magnitude of the average velocity for its motion from $A$ to
$F$ is $v/5$
$B$ is $v$
$\frac{{\sqrt 3 v}}{2}$
All of the above
Two balls are thrown horizontally from the top of a tower with velocities $v_1$ and $v_2$ in opposite directions at the same time. After how much time the angle between velocities of balls becomes $90^o$ ?
If position time graph of a particle is sine curve as shown, what will be its velocity-time graph.
$v-t$ graph of an object of mass $1\,\, kg$ is shown
The figure shows the velocity and the acceleration of a point like body at the initial moment of its motion. The direction and the absolute value of the acceleration remain constant. Find the time when the speed becomes minimum.........$s$ (Given : $a = 4\, m/s^2, v_0 = 40\, m/s, \phi =143^o$)
A particle moves in the $xy$ -plane with velocity $u_x = 8t -2$ and $u_y = 2$. If it passes through the point $(14, 4)$ at $t = 2\, s$, the equation of its path is
