Question: Part (a) Enter an expression, in Cartesian unit-vector notation, for the average acceleration of the car during the given time period using the symbols provided.

Part (a) Enter an expression, in Cartesian unit-vector notation, for the average acceleration of the car during the given time period using the symbols provided.

A car moves along a horizontal road with constant velocity y Vo = vox i = (44.6 m/s) i until it encounters a smooth inclined hill. It climbs the hill with constant velocity VI = VI,x i + VI,y j = (44.7 m/s) i + (1.88 m/s) j as indicated in the figure. The period of time during which the car changes its velocity is At = 2.29 s
