Study the given graph and answer the following questions

$(i)$ Which part of the graph shows accelerated motion ?

$(ii)$ Which part of the graph shows retarded motion ?

$(iii)$ Calculate the distance travelled by the body in first $4$ seconds of journey graphically.

Define acceleration. State a relationship connecting $u, v, a$ and $t$ for an accelerated motion. Give an example of a motion in which acceleration is uniform.

Study the speed$-$time graph of a car below and answer the following questions

$(a)$ What type of motion is represented by $OA$ ?

$(b)$ Find acceleration from $B$ to $C$.

$(c)$ Calculate the distance covered by the body from $A$ to $B$.

The distance$-$time graph of a body is parallel to time axis. The body is

An object is moving along a straight line with uniform acceleration. The following table gives the velocity of the object at various instants of time

Plot the graph.

From the graph.

$(i)$ Find the velocity of the object at the end of $2.5 sec$

$(ii)$ Calculate the acceleration.

$(iii)$ Calculate' the distance covered in the last $4$ sec.
