HW 2.A : pp. 57-59: 8,9,12,13,16,17,20,26,34,35,38,39.. HW 2.B: pp. 60-61: 46,47,48,50,52, 58,59,61. ,70,71,72-75,80.. Learning Objectives for Chapter 2. Students will understand the general relationships among position, velocity, and acceleration for the motion of a particle along a straight line so that given a graph of one of the kinematics quantities, position, velocity, or acceleration, as a function of time, they can:. The Equation. Describe how you could measure the acceleration of a small vehicle as it runs down a slope in the laboratory.. TASK. Many different ways. https://www.youtube.com/watch?v=YUqwdD73610. There are different ways to measure acceleration here are a few..
