Question
inute.1-If a new person with mass 104 kg rides the ride, what minimum coefficient of friction between the wall and the person would be needed?
2-Which of the following changes would decrease the coefficient of friction needed for this ride?
a-increasing the rider's mass
b-increasing the radius of the ride
c-increasing the speed of the ride
d-increasing the acceleration due to gravity (taking the ride to another planet)
3-To be safe, the engineers making the ride want to be sure the normal force does not exceed 2.2 times each persons weight - and therefore adjust the frequency of revolution accordingly. What is the minimum coefficient of friction now needed?
Explanation / Answer
