The maximum speed that a car can travel around a flat curved road is 18m/s. What would be the maximum speed for that car around a curve with half the radius?

• physics -

assuming friciton was the same,

original friction=mv^2/r=m18^2/r

original friction2= mV^2/(r/2)

divide the first equation by the second

1=18^2/v^2 (1/2)
solve for v
