velocity question help??? 1. The problem statement, all variables and given/known data A car is going at 50 km/h due east. Water is falling vertically with respect to the earth. Looking at the side windows the water creates a 60 degree angle with the vertical. What is the velocity of the water with respect to a) car b) earth. 2. Relevant equations I don't know how to solve, so I don't know any relevant equations. 3. The attempt at a solution Did not know how to approach. Could someone please clear this up for me. These type of "with respect to" questions are really confusing for me.
