The initial velocity of the particle is $10\,m/\sec $ and its retardation is $ 2\;m/sec^2$. The distance moved by the particle in $5^{th}$ second of its motion is..........$m$

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 $0.5\,s ...........\,m$

A bullet fired into a fixed target loses half of its velocity after penetrating $3\, cm$. How much further will it penetrate before coming to rest assuming that it faces constant resistance to motion.........$cm$

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

What is the relation between displacement, time and acceleration in case of a body having uniform acceleration

A small toy starts moving from the position of rest under a constant acceleration. If it travels a distance of $10 \,m$ in $t \;s ,$ the distance travelled by the toy in the next $t s$ will be .........$m$
