NCERT Solutions for Chapter: Motion, Exercise 5: Questions

A bus starting from rest moves with a uniform acceleration of $0.1 \mathrm{m}/{\mathrm{s}}^2$ for $2 \mathrm{minutes}$. Find the speed acquired.

A bus starting from rest moves with a uniform acceleration of $0.1 \mathrm{m}/{\mathrm{s}}^2$ for $2 \mathrm{minutes}$. Find the distance travelled.

A train is travelling at a speed of $90 \mathrm{k}\mathrm{m}/\mathrm{h}$. Brakes are applied so as to produce a uniform acceleration of $-0.5 \mathrm{m}/{\mathrm{s}}^2$. Find how far the train will go before it is brought to rest.

A trolley, while going down an inclined plane, has an acceleration of $2 \mathrm{c}\mathrm{m} {\mathrm{s}}^{-2}$. What will be its velocity $3 \mathrm{s}$ after the start?

A racing car has a uniform acceleration of $4 \mathrm{m}/{\mathrm{s}}^2$. What distance will it cover in $10 \mathrm{s}$ after start?

A stone is thrown in a vertically upward direction with a velocity of $5 \mathrm{m}/\mathrm{s}$. If the acceleration of the stone during its motion is $10 \mathrm{m}/{\mathrm{s}}^2$ in the downward direction, what will be the height attained by the stone and how much time will it take to reach there?
