A particle moves with constant acceleration, let $v_1, v_2, v_3$ be the Average velocities in successive time interval $t_1, t_2$ and $t_3$ then
$\frac{{{v_1}\, - \,{v_2}}}{{{v_2}\, - \,{v_3}}}\, = \,\frac{{{t_1}\, - {t_2}}}{{{t_1}\, + \,{t_2}}}$
$\frac{{{v_1}\, - \,{v_2}}}{{{v_2}\, - \,{v_3}}}\, = \,\frac{{{t_1}\, - {t_2}}}{{{t_1}\, - \,{t_3}}}$
$\frac{{{v_1}\, - \,{v_2}}}{{{v_2}\, - \,{v_3}}}\, = \,\frac{{{t_1}\, + {t_2}}}{{{t_2}\, + \,{t_3}}}$
$\frac{{{v_1}\, - \,{v_2}}}{{{v_2}\, - \,{v_3}}}\, = \,\frac{{{t_1}\, - {t_2}}}{{{t_2}\, - \,{t_3}}}$

The velocity of bullet is reduced from $200\; m / s$ to $100\; m / s$ while travelling through a wooden block of thickness of $10 \;cm$ . The retardation assuming to be uniform, will be ...........$\times {10^4}\, m/s^2$
The ratio of displacement in $n$ second and in the $n^{th}$ second for a particle moving in a straight line under constant acceleration starting from rest is
A bus is moving with a velocity $10 \,m/s$ on a straight road. A scooterist wishes to overtake the bus in $100\, s$. If the bus is at a distance of $1 \,km$ from the scooterist, with what velocity should the scooterist chase the bus......... $m/s$
A ball of mass $m_1$ and another ball of mass $m_2$ are dropped from equal height. If time taken by the balls are $t_1$ and $t_2$ respectively, then
