RELATIVE-MOTION ANALYSIS OF TWO PARTICLES USING TRANSLATING AXES Today’s Objectives: Students will be able to: 1. Understand translating frames of reference. 2. Use translating frames of reference to analyze relative motion. In-Class Activities: Check Homework, Reading Quiz Applications Relative Position, Velocity and Acceleration Vector & Graphical Methods Concept Quiz Group Problem Solving Attention Quiz
READING QUIZ 1. The velocity of B relative to A is defined as A) vB vA .B) vA C) vB + vA .D) vA + v B . v B . 2. Since two dimensional vector addition forms a triangle, there can be at most _________ unknowns (either magnitudes and/or directions of the vectors).
APPLICATIONS Here, the boy on the ground is at d = 10 ft when the girl in the window throws the ball to him. If the boy on the ground is running at a constant speed of 4 ft/s, how fast should the ball be thrown?When you try to hit a moving object, the position, velocity, and acceleration of the object all have to be accounted for by your mind.You are smarter than you thought!
