4. a certain light truck can go around a flat curve having a radius of 150 m with a maximum speed of 32.0 m/s. with what maximum speed can it go around a curve having a radius of 75.0 m?

The maximum speed would be 22.63 m/s.According to the centripetal force, force is the product of the mass and square of the velociy divided by radius of the curve.F = [tex]\frac{mv^{2} }{r}[/tex]where m is the mass of the object, v is the velocity of the object and "r" is the radius of the curve.where F can also be written as , F = mawhere a is the accelerationma =  [tex]\frac{mv^{2} }{r}[/tex]a = v^2/rAccording to the question, first casea = v^2/r = 32^2/150 = 6.83 m/s^2Now coming to the second part, we can write that v = [tex]\sqrt{ar}[/tex]v = [tex]\sqrt{6.83*75}[/tex]  =  [tex]\sqrt{512}[/tex]v = 22.63 m/sHence the maximum speed is 22.63 m/sFor more information about centripetal force, visit herehttps://brainly.com/question/11324711#SPJ4
