Quiz: Test 9-10 with Fin: X + | ivyleam.ivytech.edu/courses/737548/quizzes/1723571/take A popular amusement park ride has a radius of 3.0 m and is set into circular motion at an angular speed of = 6 rad/s, as shown in the figure. The floor drops away and the person remains suspended against the vertical wall. What is the minimum coefficient of friction necessary to keep the rider from slipping? lvy Learn Question 6 5 pts Courses 0.0 N 30.00 0 Inbox 12.0 N 9.00 N Help Suppose a - 11 cm and b 23 cm.

Explanation / Answer

centripetal force is

Fc = mr²

which will be the normal force of the wall on the rider

Friction force must equal gravity force to keep the rider from slipping

mr² = mg

r² = g

= g / r²

= 9.81 / 3(6.0)²

= 0.09083 minimum
