Refer to Problem $13\mathrm{.}119$ and $13\mathrm{.}120$ of the Bedford and Folwer textbook. If the car increases its speed at a constant rate from $36$ mi$/$hr at A to $49$ mi$/$hr at B$,$ determine the tangential component of acceleration as it travels along the road. Determine the normal component of acceleration after the car has traveled $120$ ft from A$.$What is the normal component of acceleration after the car has traveled $170$ ft from A$?$
