The position, velocity and acceleration of a particle moving with a constant acceleration can be represented by

If body having initial velocity zero is moving with uniform acceleration $8\,\,m/{\sec ^2}$ the distance travelled by it in fifth second will be.........$metres$

A particle moves in a straight line with a constant acceleration . It changes its velocity from $10 \,ms^{-1 }$ to $ 20\, ms^{-1 }$ while passing through a distance $135\,m$ in $t$ second. The value of $t$ is..........$s$

The same retarding force is applied to stop a train. The train stops after $80\, m$. If the speed is doubled, then the stopping distance will be

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 ........$s$

A motor car moving at a speed of $72\,km / h$ cannot come to a stop in less than $3.0\,s$ while for a truck this time interval is $5.0\,s$. On a highway, the car is behind the truck both moving at $72\,km / h$. The truck gives a signal that it is going to stop at emergency. At what distance the car should be from the truck so that it does not bump onto (collide with) the truck. Human response time is $0.5\,s ...........\,m$
