A hiker rides $700\, m$ north, $300$ meast, $400 \,m$ north $600\, m$ west, $1200\, m$ south, $300\, m$ east and finally $100\, m$ north. Draw the path of motion of the biker. What distance did he cover ? What was his displacement ?

For the motion on a straight line path with constant acceleration the ratio of the maqnitude of the displacement to the distance covered is

State the meaning of uniform circular motion.

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

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

$(i)$ What type of motion is represented by $OA, AB$ and $BC$ ?

$(ii)$ Find positive and negative accelerations of the body.

$(iii)$ Find the distance travelled by the body from $A$ to $B$.
