An object is moving with uniform speed in a circle of radius $7 \, m$. Calculate the distance and displacement when it completes half the circle. What type of motion does the object possess?

The average time taken by a normal person to react to an emergency is $1/15$ of a second and is called the 'reaction time'. If a bus is moving with a velocity of $60 \, km/h$ and its driver sees a child running across the road,how much distance would the bus have moved before he could press the brakes? The reaction time of the people increases when they are intoxicated. How much distance would the bus have moved if the reaction time of the driver were $1/2 \, s$ under the influence of alcohol?

What conclusion can you draw from the displacement$-$time graph of a body shown below?

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

Write any two equations of motion for a body having uniform acceleration.

Ravi told his friend that his house is $1 \,km$ toward south from the main Post Office. Express the displacement and the distance moved by the friend from the Post Office when he arrives at Ravi's house. Mention the reference point chosen by you.
