Acurving freeway exit has a radius of 50 m and a posted speed limit of 35 mph. what is your radial acceleration if you take this exit at the posted
speed? use 1 mph = 0.447 m/s.
4.9 m/s2
6.3 m/s2
0.3 m/s2
2.5 m/s2

The radial acceleration, a = 4.9 m/s²

Explanation:

Given,

The radius of the curve,   r = 50 m

The speed limit of the curve, v = 35 mph

                                                   = 15.645 m/s

The radial acceleration of the car is given by the formula,

                                      a = v² / r

Substituting the given values in the above equation

                                        a = 15.645 / 50

                                           = 4.9 m/s²

Hence, the radial acceleration of the car is, a = 4.9 m/s²                      

i would think it's food chain
