please see below

Explanation:

The automobile's tangential acceleration is a=0.500 ms^-2a=0.500ms2(given,as rate of increase in velocity=acceleration)

)At an instant when the instantaneous speed of the automobile is v=4 ms^-1v=4ms1

It's, centripetal acceleration(a') = v^2/r = 16/20 =0.8 ms^-2

And,total acceleration = sqrt(a^2 + a'^2)=0.943 ms^-2

Making an angle of tan^-1((a')/a)=58^@ w.r.t the automobile's path.enter image source here
