$0$ to $2\,\,s$
$2$ $4\,\,s$
$4$ to $6 \,\,s$
$6$ to $8\,\, s$
Find the value of Relative velocity of any two particles moving in a frame of reference.
A man on a rectilinearly moving cart, facing the direction of motion, throws a ball straight up with respect to himself
Explain average velocity ,instantaneous velocity and components of velocity for motion in a plane.
Two particles start simultaneously from the same point and move along two straight lines, one with uniform velocity $v$ and other with a uniform acceleration $a.$ If $\alpha$ is the angle between the lines of motion of two particles then the least value of relative velocity will be at time given by
A particle starts from rest and performing circular motion of constant radius with speed given by $v = \alpha \sqrt x$ where $\alpha$ is a constant and $x$ is the distance covered. The correct graph of magnitude of its tangential acceleration $(a_t)$ and centripetal acceleration $(a_c)$ versus $t$ will be:
