Example 2 The figure below is a graph of a particle's position along an x axis versus time. (a) At time t = 0, what is the sign of the particle's position? Is the particle's velocity positive, negative, or 0 at (b) t = 1 s, (c) t = 2 s, and (d) t = 3 s? (e) How many times does the particle go through the point x = 0?

Unformatted text preview: 2 times Example 3 The figure below gives the velocity of a particle moving along an axis. Point 1 is at the highest point on the curve; point 4 is at the lowest point; and points 2 and 6 are at the same height. What is the direction of travel at (a) time t = 0 and (b) point 4? (c) At which of the six numbered points does the particle reverse its direction of travel? (d) Rank the six points according to the magnitude of the acceleration, greatest first. Answers to Example 3 a. Positive b. Negative c. 3,5 d. 2 and 6, 3 and 5, 1 and 4 Example 4 Answers to Example 4 a. 19.6 m b. 58.8 m...
