A rope is wrapped around the equator of a perfectly spherical Earth (circumference of 131,480,000 feet). This rope is cut and a piece is added in. The rope is now rearranged so that it is at a uniform height of 1 foot above the equator. How long was the piece that was added in?

A light rope is wrapped several times around a large wheel with a radius of 0.405 m . The wheel rotates in frictionless bearings about a stationary horizontal axis, as shown in the figure (Figure 1) . The free end of the rope is tied to a suitcase with a mass of 13.0 kg . The suitcase is released from rest at a height of 4.00 m above the ground. The suitcase has a speed of 3.15 m/s when it...

A light rope is wrapped several times around a large wheel with a radius of 0.395 m. The wheel rotates in frictionless bearings about a stationary horizontal axis, as shown in the figure (Figure 1). The free end of the rope is tied to a suitcase with a mass of 16.5 kg. The suitcase is released from rest at a height of 4.00 m above the ground. The suitcase has a speed of 3.00 m/s when it reaches the ground....

Many communication satellites are placed in a circular orbit around the Earth at a radius where the period (the time to go around the Earth once) is 24 hours. If the satellite is above some point on the equator, it stays above that point as the Earth rotates, so that as viewed from the rotating Earth the satellite appears to be motionless. That is why you see dish antennas pointing at a "fixed" point in space. (a) Calculate the radius...

5.168 The Earth has a radius of approxinh ever 6000 km and rotates around its axis every 24 h. James begins at the South Pole and flies, drives, and boats so that he is always going due North at 50 km/h. (Note that he maintains a distance of 6000 km from the center of the Earth-the origin-and that while he trav- els North, he is also spinning with the Earth.) We take the axis of rotation as our z-axis. (a)...

Thanks so much ahead of time!
A spherical shell of radius 0.43 m and mass 27 kg initially rolls without slipping towards an incline at a linear speed of 9.1 m/s. If the ball rolls up an incline (inclined 35 degrees above the horizontal) without sliding. How high will it go? A professor holding a spinning wheel used for a demonstration brings the wheel to a stop by applying a constant, tangential friction force to the edge (his hand). The...

Question 1
(a)What is the angular frequency
of a satellite that orbits the Earth just above the surface?
Ignore air resistance . Radius of Earth is Re and
centripetal acceleration is ac = (v2)/R. The
acceleration at Earth's surface is a = g =
(GMe)/(Re2) where Me =
mass of Earth. Keep your answer in terms of G, Me,
Re.
