acceleration of car, \(\displaystyle{a}_{{1}}={\left(-{\cos{{\left({35}\right)}}}{i}+{\sin{{\left({35}\right)}}}\right)}\cdot{a}\)

\(\displaystyle{a}_{{1}}=-{0.27}{i}+{0.19}{j}\)

the acceleration when the car is at B located at an angle of 35.0 is \(\displaystyle{\left(-{0.27}{i}\ \frac{{m}}{{s}^{{2}}}+{0.19}{j}\ \frac{{m}}{{s}^{{2}}}\right)}\)

(b) the car average speed is v

the car average speed is 7.12\ m/s

c) initial speed of car, \(\displaystyle{u}_{{1}}={7.12}{i}\ \frac{{m}}{{s}}\)
