1.) A car rounds a banked curve where the radius of curvature for the road is R, the banking angle is 0(theta), and the coefficient of static friction is [mu]. (a) Determine the range of speeds the car can have without slipping up or down the road. (b) What is the range of speeds possible if R = 100m, 0(theta)=10, and [mu]=0.10 (slippery conditions)????(adsbygoogle = window.adsbygoogle || []).push({});

2.) In a popular amusement park ride, a rotating cylinder of radium 3.00m is set in rotation at an angular speed of 5.00rad/s. The floor then drops away, leaving the riders suspended against the wall in a vertical position. What minimum coefficient of friction between a rdier's clothing and the wall is needed to keep the rider from slipping?????? (hint: recall that the magnitude of the max force of static friction is equal to [mu]n, where n is the normal force - in this case, the force causing the centripetal acceleration.

DAMN YOU ROTATIONAL MOTION AND CENTRIPETAL ACCELERATION. I HATE YOU!!$!$!)(
