Velocity of a body moving along a straight line with uniform acceleration $a$ reduces by $\frac{3}{4}$ of its initial velocity in time $t_0$. The total time of motion of the body till its velocity becomes zero is
$\frac{4}{3} t_0$
$\frac{3}{2} t_0$
$\frac{5}{3} t_0$
$\frac{8}{3} t_0$
A car is moving along a straight road with a uniform acceleration. It passes through two points $P$ and $Q$ separated by a distance with velocity $30\; km / h$ and $40\; km / h$ respectively. The velocity of the car midway between $P$ and $Q$
An object accelerates from rest to a velocity $27.5 \,m/s$ in $10 \,sec$ then find distance covered by object in next $10\, sec$........$m$
A particle starts from rest and traverses a distance $l$ with uniform acceleration, then moves uniformly over a further distance $2 l$ and finally comes to rest after moving a further distance $3 l$ under uniform retardation. Assuming entire motion to be rectilinear motion the ratio of average speed over the journey to the maximum speed on its ways is
