A car, travelling at speed v, can safely negotiate an unbanked curve with a 50.0-m radius when the coefficient of friction between the tires and the road is 0.8. How much bank would a curve with the same radius require if the car is to safely go around it at the same speed, v, without relying on friction?(adsbygoogle = window.adsbygoogle || []).push({});

my work:

Msmg=Fr=m((v^2)/r)

(0.8)(9.8m/s^2)=(v^2)/(50m)=19.79m/s

Mgsinx=Fr=m((v^2)/r)

(9.8)sinx=(19.79m/s)/(50m)=53.13 degree

please tell me if i am wrong or right
