Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal for…

Chapter 13, Problem 13.80CP

CP Tidal Forces near a Black Hole. An astronaut inside a spacecraft, which protects her from harmful radiation, is orbiting a black hole at a distance of 120 km from its center. The black hole is 5.00 times the mass of the sun and has a Schwarzschild radius of 15.0 km. The astronaut is positioned inside the spaceship such that one of her 0.030-kg ears is 6.0 cm farther from the black hole than the center of mass of the spacecraft and the other ear is 6.0 cm closer. (a) What is the tension between her cars? Would the astronaut find it difficult to keep from being torn apart by the gravitational forces? (Since her whole body orbits with the same angular velocity, one ear is moving too slowly for the radius of its orbit and the other is moving too fast. Hence her head must exert forces on her ears to keep them in their orbits.) (b) Is the center of gravity of her head at the same point as the center of mass? Explain.

A spacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1 500 kg. It has strayed too close to a black hole having a mass 102 times that of the Sun. The nose of the spacecraft points toward the black hole, and the distance between the nose and the center of the black hole is 10.0 km. Black hole -100 m- (a) Determine the total force on the spacecraft. N 10.0 km (b) What is the difference in the gravitational fields acting on the occupants in the nose of the ship and on those in the rear of the ship, farthest from the black hole? (This difference in acceleration grows rapidly as the ship approaches the black hole. It puts the body of the ship under extreme tension and eventually tears it apart.) N/kg

A spacecraft in the shape of a long cylinder has a length of 100 m, and its mass with occupants is 1 050 kg. It has strayed too close to a black hole having a mass 103 times that of the Sun. The nose of the spacecraft points toward the black hole, and the distance between the nose and the center of the black hole is 10.0 km. Black hole -100 m 10.0 km (a) Determine the total force on the spacecraft. A black hole can be treated in the same manner as any other point mass and used in the equation for the gravitational force as long as you are outside the Schwarzschild radius. N (b) What is the difference in the gravitational fields acting on the occupants in the nose of the ship and on those in the rear of the ship, farthest from the black hole? (This difference in acceleration grows rapidly as the ship approaches the black hole. It puts the body of the ship under extreme tension and eventually tears it apart.) N/kg

One way astrophysicists have identifi ed “extrasolar” planets orbiting distant stars is by observing redshifts or blueshifts in the star’s spectrum due to the fact that he star and planet each revolve around their common center of mass. Consider a star the size of our sun (mass 1.99 x 1030 kg), with a planet the size of Jupiter(1.90 x 1027 kg) in a circular orbit of radius 7.79 x 1011 m and a period of 11.9 years. (a) Find the speed of the star revolving around the system’s center of mass. (b) Assume that Earth is in the planet’s orbital plane, so that at one point in its orbit the star is moving directly toward Earth, and at the opposite point it moves directly away from Earth. How much is 550-nm light redshifted and blueshifted at those two extreme points?
