Summary Lecture 4 Summary Lecture 4 { Adding Vectors: Relative Velocity e.g. a helicopter flying due west with wind blowing from the south. 40 km/h ß 125 km/h Magnitude of resultant velocity of resultant velocity: v Heli-Ground 2 = v Heli-Air. 2 + v Air-Ground 2 Direction tan (ß) = v Ai Ground /v Hel Ai Direction: tan (ß) v Air-Ground Heli-Air With respect to ground the helicopter flies with this speed along that direction

Unformatted text preview: 3. What quantities are known? 4. Analyze the horizontal (x) and the vertical (y) motion separately. 5. Think (again) Horizontal Motion (x, no acceleration) a x = 0 (no x acceleration) v = v (x velocity is constant v x = v ox (x-velocity is constant) x = x o + v ox t Vertical Motion (y positive upward) v y = v oy + a y t (Free Fall, a y = -9.8m/s 2 ) y = y o + v oy t + 1 / 2 a y t 2 v y 2 = v oy 2 + 2a y (y-y o )...
