Heena Sharma, Shubhankat Vats and, Rashmi Gupta Solutions for Chapter: Motion, Exercise 5: CHAPTER EXERCISE

Look at the figure below and answer the following questions:

Name the kind of motion of the stone.

Look at the figure below and answer the following questions:

Is this an example of accelerated motion? Why?

Look at the figure below and answer the following questions:

Name the force that keeps the stone in its path.

Look at the figure below and answer the following questions:

What is the direction of this force? Draw it in your answer sheet.

Figure shows $\mathrm{x}-\mathrm{t}$ graph of a particle moving along a straight line. What is the sign of the acceleration during the intervals $\mathrm{O}\mathrm{A},\mathrm{}\mathrm{A}\mathrm{B},\mathrm{}\mathrm{B}\mathrm{C}$ and $\mathrm{C}\mathrm{D}$?

Write three equations of uniformly accelerated motion. Also, state the symbols used.

An object starting from rest travels $20 \mathrm{m}$ in first $2 \mathrm{s}$ and $160 \mathrm{m}$ in next $4 \mathrm{s}$. What will be the velocity after $7 \mathrm{s}$ from the start?

Obtain a relation for the distance travelled by an object moving with a uniform acceleration in the interval between $4^{th}$and $5^{th}$ second.
