Acar moves along a horizontal road with constant velocity v0 = v0xiuntil it encounters a smooth inclined hill, which it climbs with constant velocity v1 = v1xi + v1yj as indicated in the figure. the period of time during which the car changes its velocity is δt. variablesv0x = 36 m/sv1x = 34 m/sv1y = 1.1 m/sδt = 1.4 spart a. give a vector expression for the average acceleration of the car during the given time period in terms of the variables in the problem and unit vectors i and j.
