Q. 10 FIGURE EX1.10 shows two dots of ... [FREE SOLUTION]

Chapter 1: Q. 10 (page 29)

FIGURE EX1.10 shows two dots of a motion diagram and vector $\overset{鈫�}{v_{1}}$ . Copy this figure, then add dot 3 and the next velocity vector $\overset{鈫�}{v_{2}}$ if the acceleration vector $\overset{鈫�}{a}$ at dot 2
(a) points up and (b) points down.

Short Answer

Expert verified

The vector diagrams are shown.

Step by step solution

Step1. write the given information

Points 1 and 2 are the position of the object with respect to time. The vector sign shows the direction of the velocity of the object

Step 2. i) To draw a point above point 2 such that acceleration is upwards

The acceleration of the body is a change in velocity with respect to time. The next dot should be added above point 2 such that the distance between points 1 and 2 is less than the distance between points 2 and 3.

The acceleration at point 2 is upwards.

Step 3. ii) To draw a point above point 2 such that acceleration is downwards

The acceleration at point 2 would be downwards when the velocity of the object between points 2 and 3 is less than the velocity between points 1 and 2 as shown in the figure.

The average acceleration at point 2 is downwards.
