Hint, the kinemaOc equaOon that describes each leg of the trip that is valid for constant velocity is x ­xo= vt. This equaOon is valid if the velocity vector and displacement vectors are with respect to the same frame. In this case, the displacement is with respect to the ground, so the required velocity is with respect to the ground, or vjg! Use Galilean formula to write vjg in terms of velocity that is given and wind velocity that is wanted. Quiz Week 6  ­Problem 1 ­ Soln •  A passenger train is traveling due west at 10 km/hr. Rain is falling straight down at 20 km/hr. What is the velocity vector, vrt , of the raindrops with respect to an observer that is siFng on the train (imagine the raindrops being viewed are just off the window)? 1.  2.  Define coordinate system : +j direcOon is up, +x is East IdenOfy 1.  2.  3.  3.  frame A = ground symbol=g frame B = train symbol= t Object P = raindrop symbol= r Write given velociOes in vector notaOon us...
