Chapter 1: Q. 12 (page 29)

A speed skater accelerates from rest and then keeps skating at a constant speed. Draw a complete motion diagram of the skater

Short Answer

Expert verified

The motion diagram of the skater is shown

Step by step solution

01

Step 1. Write the given information

The skater first accelerates and then she moves at a constant speed.

In the motion diagram, each dot represents the position of the skater, with respect to time.
The more space between the dots represents the distance covered by the skater in the given time interval is more.

02

Step 2. To draw the motion diagram

The skater starts accelerating first. This implies at point 1, the skater would accelerate toward the right as shown in the figure. Thereafter, the skater would move with constant speed. Thus the acceleration at points 2 and 3 is shown as zero.

The skater accelerates from 0 to 1 towards the right.

The acceleration at points 2 and 3 is zero.

and why is it important?

b. Give two examples of situations, different from those

described in the text, for which the particle model is appropriate.

c. Give an example of a situation, different from those described in the text, for which it would be inappropriate.
