an object with a mass of 0.5 kg is doing uniforma cicular motion, the circle radius is 1.2 meters and 20 turns time is 33 seconds, how much is the centripetal force? O 12 N O 42.5 N O 87 N O 8.69 N

Assume the Moon travels in a perfect circle around the Earth, with masses 7.35 * 1022 kg and distances 3.85 * 105km and takes 27.32 days to complete a complete circle. What is the centripetal force (in N) acting on the Moon?

High-speed ultracentrifuges are useful devices to sediment materials quickly or to separate materials. An ultracentrifuge spins a small tube in a circle of radius 10.5 cm at 60000.0 rev/min. What is the centripetal force experienced by a sample that has a mass of 0.00330 kg?

A communications satellite orbits around Earth. Earth has a radius of 6380 km, and the satellite orbits 1140 km above Earth's surface. The satellite has a mass of 915 kg, and moves with a velocity of 7280 m/s. Based on this information, what is the centripetal force exerted on the satellite?   6450 N   89,900 N   14,700 N   8710 N

An object in a circular orbit is moving at a constant speed. This is called centripetal acceleration. Yet the speed is constant. How is it accelerating?

An astronaut orbiting the Earth is preparing to dock with a Westar VI satellite. The satellite is a circular orbit 500 km above the Earth's surface, where the free-fall acceleration is 8.11 m/s2. Take the radius of the Earth as 6400 km. Determine the speed of the satellite. m/s Determine the time interval required to complete one orbit around the Earth, which is the period of the satellite. min

A satellite with mass of 4.2 x 105 kg that is 400 km from the ground is orbiting at 7.6 km/s around Earth. What is the centripetal force??

A car has an acceleration of 2 m/s/s as it moves in a circle. What is its velocity if the circle has a radius of 17m? *   2 m/s/ 5.8 m/s 17 m/s 60 m/s

A 70 kg person on a merry go round is spinning with speed 5 m/s. If they experience a centripetal force of 583N, how far from the center of the merry go round are they sitting? Express in meters.

The Earth spins at 460 meters per second at the equator. The radius of the Earth is 6.37 x 106 m. A person who believes in a flat Earth says that if the Earth was round and spinning that fast we would all fly off. Imagine if you were standing inside a hollow earth. How much centripetal acceleration would you experience? How does this compare to the acceleration due to gravity we feel at the Earth’s surface? Does it explain why we don’t fly off the Earth due to the spin?
