Engineering Mechanics Dynamics · R.C. Hibbeler · Chapter 12

Course: Engineering Mechanics Dynamics Book: R.C. Hibbeler Chapter: Chapter 12

Question

Starting from rest at $s = 0$, a boat travels in a straight line with the acceleration described by the following piecewise linear a-s graph: - From $s = 0$ to $s = 100$ ft: acceleration decreases linearly from $a = 8$ ft/s² to $a = 6$ ft/s² - From $s = 100$ ft to $s = 150$ ft: acceleration decreases linearly from $a = 6$ ft/s² to $a = 0$ ft/s² Determine the boat's speed when $s = 50$ ft, $s = 100$ ft, and $s = 150$ ft.
