A roller coaster has a "hump" and a "loop" for riders to enjoy (see picture). The top of the hump has a radius of curvature of 1
nikklg [1K]

Answer:

Part a)

F_n = 306 N

Part B)

v = 12.1 m/s

Explanation:

Part A)

At the top of the hump the force on the rider is

1) Normal force

2) weight

so here we know that

mg - F_n = \frac{mv^2}{R}

F_n = mg - \frac{mv^2}{R}

F_n = (100)(9.81) - \frac{100(9^2)}{12}

F_n = 306 N

Part B)

At the top of the loop we will have

F_n + mg = \frac{mv^2}{R}

in order to remain in contact the normal force must be just greater than zero

so we will have

mg = \frac{mv^2}{R}

v = \sqrt{Rg}

v = \sqrt{15\times 9.81}

v = 12.1 m/s
