A particle starting from rest and moves with constant acceleration travels a distance $x$ in first $2$ seconds and a distance $y$ in next two seconds, then
$y = x$
$y = 2x$
$y = 3x$
$y = 4x$
Two cars leave one after the other and travel with an acceleration of $0.4\, m/s^2$. Two minutes after the departure of the first, the distance between the cars becomes $1.9\, km$. The time interval between the departures of the cars is ........$s$
Which graph represents the uniform acceleration
A body of mass $10\, kg$ is moving with a constant velocity of $10 \,m/s$. When a constant force acts for $4 \,seconds$ on it, it moves with a velocity $2 \,m/sec$ in the opposite direction. The acceleration produced in it is...........$m/{\sec ^2}$
