1) What is the speed of a person ?stuck? to the wall? (15.6)

2) What is the normal force of the wall on a riderof m = 51 kg? (1748)

3) What is the minimum coefficient of friction needed betweenthe wall and the person? (0.28)

4) If a new person with mass 102 kg rides the ride, what minimumcoefficient of friction between the wall and the person would beneeded?(0.28)

i need help in these two

5)Which of the following changes would decrease the coefficientof friction needed for this ride?

a) increasing the rider's mass

b) increasing the radius of the ride

c )increasing the rotation rate of the ride

d )increasing the acceleration due to gravity (taking the rideto another planet)

6) To be safe, the engineers making the ride want to be sure thenormal force does not exceed 1.9 times each persons weight - andtherefore adjust the frequency of revolution accordingly. What isthe minimum coefficient of friction now needed?

2 In a classic carnival ride, patrons stand against the wall in a cylindrically shaped room. Once the room gets spinning fast enough, the floor drops from the bottom of the room! Friction between the walls of the room and the people on the ride make them the "stick" to the wall so they do not slide down. In one ride, the radius of the cylindrical room is R = 7.1 m and the room spins with a frequency of 21 revolutions per minute. 2 In a classic carnival ride, patrons stand against the wall in a cylindrically shaped room.
