R P Goyal and S P Tripathi Solutions for Chapter: Motion in One Dimension, Exercise 2: EXERCISE–2(B)

A body falls freely from a certain height. Show graphically the relation between the distance fallen and the square of time. How will you determine $g$ from this graph?

The velocity-time graph of a body in motion is a straight line inclined to the time axis. The correct statement is :
 

For a uniformly retarded motion, the velocity-time graph is :

For the uniform motion :
 

Figure shows the displacement of a body at different times

Calculate the average velocity during the time interval $5 \mathrm{s}$ to $9 \mathrm{s}$.

A body is at rest is made to fall from the top of a tower. Its displacement at different instants is given in the following table

Draw a displacement-time graph and state whether the motion is uniform or non-uniform?

The figure shows velocity-time graph for the motion of a body. Use it to find the displacement of the body at $t= 1 \mathrm{s}, 2 \mathrm{s},3 \mathrm{s}$ and $4 \mathrm{s}$, then draw displacement-time graph for it on figure (b).

A ball moves on a smooth floor in a straight line with a uniform velocity $10 \mathrm{m} {\mathrm{s}}^{-1}$ for $6 \mathrm{s}$. At $t\mathit{=}6 \mathrm{s}$, the ball hits a ball and come back along the same line to the starting point with same speed. Draw the velocity-time graph and use it to find the total distance travelled by the ball and its displacement.
