=Vfw. If you’re riding in a train moving atm/s east, this velocity is measured relative to the ground on which you’re traveling Solution Strategy for general relative velocity questions) Write the velocities of both bodies in terms of ij and) Use the relative velocity formula, v v v ab a b, to calculate the velocity of one body relative to the other. That’s a pretty big difference, but since the Earth is orbiting the sun at this speed, an observer standing on the sun (ouch!) would say that you are moving at e4 m/s. The following is a unique feature of caserelative velocity problems. •Let’s find the relative velocities of theobjects in each observers frame of reference. Example 4A1 A car and a lorry are a distance x apart on a long straight road, heading towards each other. Motion does not happen in isolation. Both of these answers are correct in their own frame of reference Analyze one-dimensional and two-dimensional relative motion problems using the position and velocity vector equations. It means that motion of any object observes the motion of the boat and river. That is V. wf. The car is It means that motion of any object is described relative to the motion of Earth. Relative to the sun: e4 m/s! •We will time how long the boat travels. •Let’s find the relative velocities of theobjects in each observers frame of reference. Then we Question of the day Relative velocity due to rotation Interpretation of vA = vB + vA/B Solution of relative-velocity equation Answer your questions! •We will time how long the boat travels. Then we can find how far up the river the boat has traveled relative to person standing on the bank, and relative to its initial position in the river Before proceeding to the next step, lets determine “the velocity of the water relative to the freighter”, V. wf. This means the size of both velocities are the same, but the directions of each are perfectly opposing You’re not moving relative to the frame of reference of the ground. ME Dynamics M4 Relative motion [In this question i and j are unit vectors due east and due north respectively] A man cycles at a constant speed u m s–1 on level What does it mean when motion is described as relative? Solution Strategy for general relative velocity questions) Write the velocities of both bodies in terms of ij and) Use the relative velocity formula, v v v ab a b, to calculate observes the motion of the boat and river.
