To design a safe turn in the road, it is important to know the constriant force. We will describe the dyncmies of such with the Langranian L(x,x,y,y) where the constraint is adaca explicitely through the degiconge mithipler (t) T0 save some time, this is all necessary knowleage - The constreint in the tern is f(x,y)=x2,y2R2=0 - The Lagienge L(x,x,y,y)=21[x2,y]=T - The equabion of molioni qiL+(t)qildcai Rewiste the equations of motion in polar coorainctes (r,) and show that, by combining them in a smat way. that the solution of is given by (t)=2M2
