Physics question-Velocity

Question

A car moves along a horizontal road with constant velocity. Vector V0=v0,x I hat (unit vector) =37.6 m/s until it encounters a smooth inclined hill. It climbs the hill with constant velocity vector v1=v1,x I hat +v1,y j hat. The period of time during which the car changes it velocity is delta 1=1.88.

A) enter an expression in cartesian unit-vector notation for the average acceleration of the car during the given time period using the symbols.

B) What is the magnitude in meters per second squared of the car's average acceleration during the given time period.
