You have an expression that relates displacement vector rs to unit vector d and an expression that relates displacement vector rs to unit vectors v and h. Substitute these expressions into the velocity expressions until you have the velocity vectors in terms of unit vectors h and v.Or method 2:The velocity vectors can be written as the sum of their "projections" along the unit vectors h and v directions. To find a "projection of a vector" in a particular direction you should dot that vector with the unit vector that defines that direction. Therefore: vector Va=(Va•h)h+(Va•v)v
