PLEASE ANSWER COMPLETE WITH BRIEF EXPLANATION IN EVERY STEP. A blue car travelling at 50 km/hr enters the curved path at point A as shown. Section AB has an arc length measuring LAB=221 m and an θAB=120∘, while sections BC and CD measure 50 m and 80 m respectively. Starting from point A, the car uniformly slows down to VD=33 km/hr at point D, then travels at a constant speed through section DE. a) Find the magnitude of the car's total acceleration in m/s2 immediately before reaching point B b) What is magnitude and direction of the car's total acceleration in m/s2 at point C ? c) Find the minimum radius of curvature of section DE in m if the car's wheels can resist a lateral (sideways) acceleration of alat,limit =1.793 m/s2 before slipping. d) Using your answer in (c), find the car's total travel time in sec if arc DE has an inside angle of θDE=130∘
