2.31. Set Up: Assume your head accelerates upward 1.0 m in 0.25 s with constant acceleration. Let be upward. and Solve: (a) and (b) No, different parts of your body travel through different distances in the same time. Reflect: The shorter the time for you to stand up, the greater the acceleration. 2.32. Set Up: Let be the direction the jet travels and take and Solve: (a) and (b) 2.33. Set Up: Let be the direction the person travels. (stops), is negative since it is opposite to the direction of the motion. Solve: so Then gives Reflect: We could also find the initial speed: 2.34. Set Up: Take the direction to be the direction of motion of the boulder. Solve: (a) Use the motion during the first second to find the acceleration. and and For the second second, and We can also solve for the location at starting at which agrees with 2.00 m in the first second and 6.00 m in the second second. The boulder speeds up so travels far- ther in each successive second. (b)
