Write the symbols of the following physical quantities:

Initial velocity, final velocity, distance, acceleration, average velocity.

Plot a velocity-time graph for a body moving under a uniform acceleration. How will you find out the distance from this graph?

What can you say about the motion of a body from the following distance-time graphs?

A car starts from rest and moves with a uniform acceleration of $4 \mathrm{m}/{\mathrm{s}}^2$. Find the final velocity of the car if it travels a distance of $800 \mathrm{m}$.

A child walks from A to E along the sides of a regular pentagon of side $10 \mathrm{m}$. Find the distance travelled by him and the magnitude of his displacement.

 A car travels at a speed of $40 \mathrm{km}/\mathrm{h}$ for $10 \min$, then at $55 \mathrm{km}/\mathrm{h}$ for $20 \mathrm{minutes}$ and finally at $20 \mathrm{km}/\mathrm{h}$ for $20 \mathrm{minutes}$. What is the average speed of the car? 

A car is moving with a velocity of $45 \mathrm{km}/\mathrm{h}$. Calculate the distance travelled by the car in​​​​​​​$1 \mathrm{h}$, $1$ minute and in $1 \sec$. 

A car starts from rest and attains a speed of $40 \mathrm{km}/\mathrm{h}$ after $10 \mathrm{seconds}$. Calculate the acceleration of the car in (i) $\mathrm{km}/{\mathrm{h}}^2$ and (ii) $\mathrm{m}/{\mathrm{s}}^2$.
