A body is moving with a velocity of $10 \mathrm{m}/\mathrm{s}$. If it starts accelerating with the rate of $2.5\mathrm{m}/{\mathrm{s}}^2$. Find out its velocity after $10 \mathrm{s}$.

If a car travels $50 \mathrm{m}$ distance in $4 \mathrm{s}$ with a acceleration of $5 \mathrm{m} {\mathrm{s}}^{-2}$, then what was its initial speed?

A cyclist is moving with a speed of $14 \mathrm{m} {\mathrm{s}}^{-1}$ He starts accelerating with a rate of $6 \mathrm{m} {\mathrm{s}}^{-2}$ and acquired the speed of $18 \mathrm{m} {\mathrm{s}}^{-1}$. Calculate, what distance did he move in acquiring that speed?

A bus is moving with a speed$72 \mathrm{km}/\mathrm{h}$can be stopped by brakes after atleast $10 \mathrm{m}$. What will be the minimum stopping distance, if the same bus is moving at a speed of $144 \mathrm{km}/\mathrm{h}$?

What do you understand by a uniform circular motion?
