The initial velocity of a car, , is 45 km/h in the

QUESTION:

The initial velocity of a car, \(\mathrm {\vec v _i}\), is  in the positive  direction. The final velocity of the car, \(\mathrm {\vec v _f}\), is  in a direction that points \(75^\circ\) above the positive  axis. (a) Sketch the vectors \(-\mathrm {\vec v _i}\), \(\mathrm {\vec v _f}\) and \(\Delta \mathrm {\vec v= \vec A_f-\vec A_i}\). (b) Find the magnitude and direction of the change in velocity, \(\Delta \mathrm {\vec v}\).
