1.2\times10^{3}\,\text{kg}

car travels at

25\,\text{m}\!\cdot\!\text{s}^{-1}

around a circular curve of radius

50\,\text{m}

that is perfectly banked so that no friction is required. What is the magnitude of the normal force exerted on the car by the road? (a)

2.7\times10^{4}\,\text{N}

(b)

1.2\times10^{4}\,\text{N}

(c)

1.9\times10^{4}\,\text{N}

(d)

1.5\times10^{4}\,\text{N}
