Slope of a velocity -time graph gives
the distance
the acceleration
the displacement
the speed
A body can have zero average velocity but not zero average speed. Justify giving an example.
Give one similarity and one dissimilarity between the two graphs
The velocity$-$time graph of a truck is plotted below
$(a)$ Calculate the magnitude of displacement of the truck in $15$ seconds.
$(b)$ During which part of the journey was the truck decelerating ?
$(c)$ Calculate the magnitude of average velocity of the truck.
A racing car has an acceleration of $4\, m s ^{-2} .$ What distance will it cover in $20$ seconds after start ?
