$A$ person travelling in a bus noted the timings and the corresponding distances as indicated on the km stones. $(a)$ Name this type of table. $(b)$ What conclusion do you draw from this data?

Time	Distance
$8.00\, am$	$10\, km$
$8.15\, am$	$20\, km$
$8.30\, am$	$30\, km$
$8.45\, am$	$40\, km$
$9.00\, am$	$50\, km$

The velocity-time graph of cars $A$ and $B$ which start from the same place and move along a straight road in the same direction is shown below.
Calculate:
$(a)$ The acceleration of car $B$ between $2 \, s$ and $4 \, s$.
$(b)$ The time at which both the cars have the same velocity.
$(c)$ The distance travelled by the two cars $A$ and $B$ in $8 \, s$.
$(d)$ Which of the two cars is ahead after $8 \, s$ and by how much?

Using the following data,draw a time-displacement graph for a moving object:

Time $(s)$	$0, 2, 4, 6, 8, 10, 12, 14, 16$
Displacement $(m)$	$0, 2, 4, 4, 4, 6, 4, 2, 0$

Use this graph to find the average velocity for the first $4 \, s$,for the next $4 \, s$,and for the last $6 \, s$.

$A$ body moves on three quarters of a circle of radius $r$. The displacement and distance The displacement and distance travelled by it are:

Name the physical quantity which corresponds to the rate of change of momentum.

Starting from rest,a scooter acquires a velocity of $36 \, km/h$ in $10 \, s$ and then brakes are applied,taking $20 \, s$ to stop. Calculate the acceleration and the total distance travelled.
