A man-made satellite orbits the earth in a circular orbit that has a radius of 21000 km. The mass of the Earth is 5.97e+24 kg. What is the tangential speed of the satellite?

The International Space Station has a mass of 440,725 kg and is located 420 km away from the surface of the earth. Earth has a mass of 5.97 x 1024 kg and a radius of 6371 km. How quickly does the ISS travel as it orbits the earth, assuming uniform circular motion? Express your answers in rev/day (for angular velocity) and mph (for tangential velocity). Define ALL variables.

An astronaut is being tested in a centrifuge. The centrifuge has a radius of 14 m and, in starting, rotates according to 0 = 0.30t2, where t is in seconds and 0 is in radians. (a) When t = 8.0 s, what is the magnitude of the astronaut's angular velocity? rad/s (b) When t = 8.0 s, what is the magnitude of the astronaut's linear speed? m/s (c) When t = 8.0 s, what is the magnitude of the astronaut's tangential acceleration? m/s? (d) When t = 8.0 s, what is the magnitude of the astronaut's radial acceleration? m/s2

A ferris wheel with a radius of 15 meters starts from rest and achieves it's maximum tangential speed of 2.4 meters per second in 33 seconds. What is the magnitude of the tangential acceleration

Riders are seated in a horizontal circle of radius 7.50 m on a carnival ride. They start from rest and accelerate uniformly for 21.0 seconds to a maximum rotational speed of 1.40 rad/s. Calculate the tangential acceleration of the riders during the first 21.0 s of the ride.

A floppy disk rotates with a constant angular speed of 56.4 rad/s.Find the tangential speed at a point 0.073 m from the axis of rotation.What is the magnitude of the centripetal acceleration at this point?
