Dr. S K Jain and Dr. Shailesh K Jain Solutions for Chapter: Motion, Exercise 3: CLASS ASSIGNMENT 3

What does the odometer of an automobile measure?

What is the nature of the distance-time graphs for uniform and nonuniform motion of an object?

An electric train is moving with a velocity of $120 \mathrm{km} {\mathrm{h}}^{-1}$. How much distance will it cover in $30 \mathrm{s}$?

What is the negative acceleration?

Draw a velocity vs time graph Of a stone thrown vertically upwards and then falling downwards after attaining the maximum height.

Define acceleration. Express the acceleration of a body in terms of its initial and final velocities. What are the units of acceleration?

A scooter acquires a velocity of $36 \mathrm{k}\mathrm{m} {\mathrm{h}}^{-1}$ in $10 \mathrm{s}$ just after the start. Calculate the acceleration of the scooter.

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