(20%) Problem 7: A car moves along a horizontal road with constant velocity until it encounters a smooth inclined hill. It climbs the hill with constant velocity v1 = V1,x i + v1,y j as indicated in the figure. A Cartesian coordinate system has been indicated. *50% Part (a) If the car moves for equal times along the road and hill, create an expression for its average velocity vector, Wave, in terms of vo,x, V1,z along with the unit vectors i and j.
