A motor car slows down from $72\, km h ^{-1}$ to $36\, km h^{-1}$ over at distance of $25\, m$. If the brakes are applied with the same force calculate $(i)$ total time in which car comes to rest $(ii)$ distance travelled by it.

Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between $4^{th}$ and $5^{th}$ seconds.

A motorcyclist drives from $A$ to $B$ with a uniform speed of $30\, km\, h^{-1}$ and returns back with a speed of $20 \,km \,h^{-1}$. Find its average speed(in $km\, h^{-1}$).

What does the slope of velocity$-$time graph represent ?

In your everyday life, you come across a range of motions in which

$(a)$ acceleration is in the direction of motion.

$(b)$ acceleration is against the direction of motion.

$(c)$ acceleration is uniform.

$(d)$ acceleration is non$-$uniform.

Can you identify one example each of the above type of motion ?
