What does the odometer of an automobile measure?

A bus starting from rest moves with a uniform acceleration of $0.5 \raisebox{1ex}{$\mathrm{m}$}\!\left/ \!\raisebox{-1ex}{${\mathrm{s}}^2$}\right.$ for $4$ minutes.
Find the speed acquired.

A bus starting from rest moves with a uniform acceleration of $0.5 \mathrm{m}/{\mathrm{s}}^2$ for $4$ minutes.
Find the distance travelled.

It took $2 \mathrm{s}$ after lightning for the sound of thunder to reach you, how far did the lightning strike?(Take speed of sound as $346 \raisebox{1ex}{$ \mathrm{m}$}\!\left/ \!\raisebox{-1ex}{$\mathrm{s}$}\right.$)

Represent the following with graph:
Non-uniform speed

State types of motion.

Derive the unit of acceleration.

A car accelerates uniformly from $20 \mathrm{km}/\mathrm{h}$ to $35 \mathrm{km}/\mathrm{h}$ in $5 \mathrm{s}$. Calculate
(a) the acceleration.
(b) the distance covered by the car in that time.
