A 50-kg ice skater goes around a circle of radius 4 m at a constant speed of 2 m/s on a level ice rink. What are the magnitude and direction of the force that the ice exerts on the skater (the total force, not just the horizontal or vertical component of the force)

2. A 6-lb slider is propelled upward from A along the curved bar that lies in a vertical plane. If the slider has a speed of 10 ft/sec as it passes B, find the magnitude of the normal force of the exerted on the slider by the rod and the rate at which the speed is changing. Neglect friction. Optional: Have half your AG do this in path, the other half do it in cylindrical and compare answers!

The other end of the spring is fixed, so that the spring is horizontal. cylinder is able to roll on the table without slipping. Let's pull the mass to one side and release it so that it rolls back and forth. The Show that the motion of the center of mass is simple harmonic, and find the frequency of ocillation, w. HINT: There are two ways (at least) to do this. Each involves comparing information about this system to the simple harmonic ocillator we know, the mass on a spring. If you can get the force/torque equation to look like -kx = max or you can get the energy budget to look like /2mv? + /2kx? = ETOTAL, then the motion…

Braving the Rotor at the Amusement Park (Circular Motion Due to Normal Force) The Rotor is an amusement park ride where people stand against the inside of a spinning cylinder, as shown below. Once the cylinder is spinning at a certain speed, the floor drops out of the bottom of the cylinder but the people do not fall out of the bottom. A conservative low estimate of the coefficient of static friction between people's clothes and the cylinder wall is 0.45. The radius of the cylinder is 2.4 m. What is the minimum number of rpm that the cylinder can have so that the people do not fall out the bottom? (answer: 29 rpm)

On a roller coaster loop-the-loop the riders are upside-down at the top of the loop, while on a Ferris wheel the riders are upright at the top. Suppose a Ferris wheel and the loop of a roller coaster have the same diameter. If riders on each have the same magnitude of apparent weight at the top, which rider is moving faster? Explain.

You have a summer internship at NASA and are working on plans for a new space station to be launched into orbit around the Earth. The design of the space station is shown. i It is to be constructed in the shape of a hollow ring of mass 52,000 kg. The structures other than the ring shown in the figure have negligible mass compared to the ring. Members of the crew will walk on a deck formed by the inner surface of the outer cylindrical wall of the ring, with radius r = 140 m. The thickness of the ring is very small compared to the radius, so we can model the ring as a hoop. At rest when constructed, the ring is to be set rotating about its axis so that the people standing inside on this deck experience an effective free-fall acceleration equal to g. The rotation is achieved by firing two small rockets attached tangentially to opposite points on the rim of the ring. Your supervisor asks you to determine the following: (a) the time interval during which the rockets must be fired if each…
