Problem

50\,\text{kg}

passenger stands on a scale in the bottom of a roller-coaster loop of radius

12\,\text{m}

. At that instant the car’s speed is

15\,\text{m}\,\text{s}^{-1}

. What is the approximate reading of the scale? (Use

g = 9.8\,\text{m}\,\text{s}^{-2}

.) a)

4.9\times10^{2}\,\text{N}

9.4\times10^{2}\,\text{N}

1.4\times10^{3}\,\text{N}

4.5\times10^{2}\,\text{N}
