Dhiren M Doshi Solutions for Chapter: Motion, Exercise 2: Check Your Progress

The distance-time graph for a body having uniform motion is a

A car moving at a uniform speed covers a distance of $200 \mathrm{m}$ in $4 \mathrm{s}$. Calculate the time it will take to cover $300 \mathrm{m}$.

A car moving at a uniform speed covers a distance of $200 \mathrm{m}$ in $4 \mathrm{s}$. Calculate the distance it will cover in $5 \mathrm{s}$.

Distinguish between the following.

Odometer and speedometer

A train takes $2 \mathrm{h}$ to reach station B from station A and then $3 \mathrm{h}$ to return from station B to station A. The distance between the two stations is $200 \mathrm{km}$. Find the average velocity of the train.

A car moving on a straight road covers a distance of $1.5 \mathrm{km}$ due east in $150 \mathrm{s}$. What is the speed of the car? What is its velocity?

The odometer of a car reads $4000 \mathrm{km}$ at the start of a trip and $4600 \mathrm{km}$ at the end of the trip. If the trip took $10 \mathrm{h}$, calculate the average speed of the car in

It takes $6$ minutes for the signal sent by an artificial satellite orbiting around the Earth to reach the ground station. Calculate the distance of the artificial satellite from the ground station. The signal travels with the speed of light, i.e. $3\times {10}^{8 }\mathrm{m}/\mathrm{s}$.
