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 makes them "stick" to the wall so they do not slide down. In one ride, the radius of the cylindrical room ris 7 m and the room spins with a frequency f of 22 revolutions per minute. Assume all quantities to be correct to 3 significant figures. (a) Draw a FBD In your notebook, draw a free body diagram of the rider. The forces acting on the rider are the frictional force that counters slipping, f, the weight, mg, and the normal force N, between the wall and the rider. Think: Which forces act in the vertical direction and which forces act in the horizontal direction. (b) Identify the centripetal force (i) What force provides the centripetal force in this case?

In Example 2.6, we considered a simple model for a rocket launched from the surface of the Earth. A better expression for the rockets position measured from the center of the Earth is given by y(t)=(R3/2+3g2Rt)2/3j where R is the radius of the Earth (6.38 106 m) and g is the constant acceleration of an object in free fall near the Earths surface (9.81 m/s2). a. Derive expressions for vy(t) and ay(t). b. Plot y(t), vy(t), and ay(t). (A spreadsheet program would be helpful.) c. When will the rocket be at y=4R? d. What are vy and ay when y=4R?
QUESTION 10 Different situation now. You re out in space, on a rotating wheel-shaped space station of radius 1249 m. You feel planted firmly on the floor , due to artificial gravity.

Express your answer in revolutions per minute (rpm). A 110.7 rpm B 0.508 rpm C 0.846 rpm D 0.089 rpmA
5 a. The following spaceship is creating artificial gravity by spinning. It's a rigid structure all making the same number of rotations each second/ it's all spinning together at the same frequency. However, chamber A and B have different radii, and so their outer walls are moving at different velocities v in m/s. Chamber B has a radius of 4 m, and someone there feels an artificial gravity acceleration of 3.215 m/s². What is VB? Previous submissions: b. What is the frequency in revolutions per second?

Circular Motion. Please answer vertically. Thank You. A string can withstand a maximum tension of 80 N without breaking. It is being used to spin a 3.0 kg weight in a circle. a) How fast can it spin without breaking if the stringis 0.75 meters long? b) If he pulls in some of the string and spins the weight in a smaller circle, will he be able to spin the weight faster? Explain why of why not?
