Suppose a mass is moving in a circular path on a frictionless table as shown in figure. In the Earth's String frame of reference, there is no centrifugal force pulling the mass away from the center of rotation, yet there is a very real force stretching the string attaching the mass to the nail. Using concepts related to centripetal force and Newton's third law, explain what force stretches the string, identifying its physical origin.

If centripetal force is directed toward the center, why do you feel that you are ‘thrown’ away from the center as a car goes around a curve? Explain.
Suppose a mass is moving in a circular path on a frictionless table as shown below. In Earth’s frame of reference, there is no centrifugal force pulling the mass away from the center of rotation, yet there is a force stretching the siring attaching the mass to the nail. Using concepts related to centripetal force and Newton’s third law; explain that force stretches the string, identifying its physical origin.
The 20-g centrifuge at NASA's Ames Research Center in Mountain View, California, is a horizontal, cylindrical tube 58 ft long and is represented in the figure below. Assume an astronaut in training sits in a seat at one end, facing the axis of rotation 29.0 ft away. Determine the rotation rate, in revolutions per second, required to give the astronaut a centripetal acceleration of 17.6g. rev/s
A space station is constructed in the shape of a wheel 20 m in diameter, with essentially all of its 5.2×105 kg mass at the rim. Once the station is completed, it is set rotating at a rate that requires an object at the rim to have radial acceleration g , thereby simulating Earth's surface gravity. This is accomplished using two small rockets, each with 130 N thrust, that are mounted on the rim of the station. How long will it take to reach the desired spin rate, and how many revolutions will the station make in this time?
A steel beam is rotating in a horizontal plane to provide the centripetal acceleration for training pilots. The pilot sits 2.81 m from the center of rotation. If the pilot experiences 3.49E3N of force as he revolves with tangible velocity of 10.6 m/s, what is the pilots mass?
To train for the physical demands of a shuttle launch, a 78.4 kg astronaut is put into a large centrifuge, where they are spun at a high speed. The centrifuge has a radius of 6.40 m, and spins with a period of 1.84 seconds. What is the centripetal force experienced by the astronaut?
If you are in a car that rounds a curve, and you are not wearing a seat belt, and you slide across your seat and slam against a car door, what kind of force is responsible for your slide—centripetal, centrifugal, or no force? Why is the correct answer “no force”?
Zorch, an archenemy of Superman, decides to slow Earth’s rotation to once per 28.0 h by exerting an opposing force at and parallel to the equator. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.00X10 N (a little greater than a Saturn V rocket’s thrust). How long must Zorch push with this force to accomplish his goal? (This period gives Superman time to devote to other villains.) Explicitly show how you follow the steps found in Problem-Solving Strategy for Rotational Dynamics.
Engineers are trying to create artificial “gravity” in a ring-shaped space station by spinning the station like a centrifuge. The ring is 100 m in radius. How quickly must the space station turn to give the astronauts inside it apparent weights equal to their real weights at Earth’s surface?
A weather satellite is to be placed in a circular orbit around the earth at an altitude of 300 miles. Itsinitial velocity in orbit is parallel to the earth's surface. What should this initial velocity be?(Hint: Get the value of acceleration due to gravity, g at the initial position of the satellite, but notconsidering the effect of the earth's rotation.)
A satellite that orbits the Earth is not physically contacting the Earth in any way. What, then, produces the centripetal force that allows for the satellite to experience uniform circular motion?
