The car travels at a constant speed from the bottom A of the dip to the top B of the hump. If the radius of curvature of the road at A is pA=120m and the car acceleration at A is 0.4g (g= 9. 81lm/s²)...

Hi, could you explain which answer is correct and why ?

thank you

Extracted text: The car travels at a constant speed from the bottom A of the dip to the top B of the hump. If the radius of curvature of the road at A is pA=120m and the car acceleration at A is 0.4g (g= 9. 81lm/s²) determine the car speed v. If the acceleration at B must be limited to 0.25g, determine the minimum radius of curvature PR of the road at B. 0.6 m G A OVA = = 21.70 m/s, pB = 191.04 m 21. 65 m/s, PB = 190. 44 m OVA = 25. 8 m/s, pB = in finite OVA = 18. 8 m/s, pB = 180. 4 m = 180.4 m
