MASSACHUSETTS INSTITUTE OF TECHNOLOGY Department of Physics Physics 8.01T Fall Term 2004 In-Class Problems 7-10: Newton’s Laws of Motion Solutions We would like each group to apply the problem solving strategy with the four stages (see below) to answer the following two problems. I. Understand – get a conceptual grasp of the problem II. Devise a Plan - set up a procedure to obtain the desired solution III. Carry our your plan – solve the problem! IV. Look Back – check your solution and method of solution In-Class Problem 7: Law of Addition of Velocities (Morning Session) a) Suppose two cars, Car A, and Car B, are traveled along roads that are perpendicular to each other. An observer is at rest with respect to the ground. A second observer is in Car r A. According to the observer on the ground, Car A is moving with a velocity v A = v A ˆ j , r and Car B is moving with a magnitude of velocity v B = v B ˆ i . What is the velocity of Car B according to the observer in Car A?
