Unformatted text preview: an x axis. What are (a) the initial and (b) the final directions of travel? (c) Does the particle stop momentarily? (d) Is the acceleration positive or negative? (e) Is it constant or varying? Answers to Example 3 (a) Negative (b) positive (c) Yes (d) positive (e) constant Example 4 The figure below gives the acceleration a versus time t for a particle moving along an x axis. The a-axis scale is set by as = 12.0 m/s2. At t = -2.0 s, the particle's velocity is 7.0 m/s. What is its velocity at t = 6.0 s? Answers to Example 4...
