Check Your Understanding Assume you are in a spacecraft in orbit about the Sun at Earth’s orbit, but far away from Earth (so that it can be ignored). How could you redirect your tangential velocity to the radial direction such that you could then pass by Mars’s orbit? What would be required to change just the direction of the velocity?
Assuming a circular orbit for the Sun about the center of the Milky Way galaxy, calculate its orbital Speed using the following information: The mass of the galaxy is equivalent to a single mass times that at the Sun (or located 30,000 ly away.
A Molniya orbit is a highly eccentric orbit of a communication satellite so as to provide continuous communications coverage for Scandinavian countries and adjacent Russia. The orbit is positioned so that these countries have the satellite in view for extended periods in time (see below). If a satellite in such an orbit has an apogee at 40,000.0 km as measured from the center of Earth and a velocity of 3.0 km/s, what would be its velocity at perigee measured at 200.0 km altitude?
Using the technique shown in Satellite Orbits and Energy, show that two masses m1 and m2 in circular orbits about their common center of mass, will have total energy E=K+E=K1+K2Gm1m2r=Gm1m22r . We have shown the kinetic energy of both masses explicitly. (Hint: The masses orbit at radii r1 and r2 , respectively, where r=r1+r2 . Be sure not to confuse the radius needed for centripetal acceleration with that for the gravitational force.)
The acceleration due to gravity near the surface of our planet is 9.82 m/s2.If we approximate Earth as a perfect sphere with a radius of 6.371 million meters, (and if we could remove air resistance and clear a pathway completely around) how fast would you need to launch an object tangentially, and very nearto the surface (as shown below) so that it would orbit with uniform circularmotion?
The Cajun Cliffhanger at Great America is a ride in which occupants line the perimeter of a cylinder and spin in a circle at a high rate of turning. When the cylinder begins spinning very rapidly, the floor is removed from under the riders' feet. What affect does a doubling in speed have upon the centripetal force? Explain.
Adam is swirling a 200 g ball that is attached to a cord of 60 cm long. If the ball is revolving in a horizontal circle at an angular speed of 5 rad/s, what is it’s centripetal force?
Can you help with subquestions 7a, 7b The merry-go-round in the park has a radius of 1.5m. If my neighbor's child (m=40 kg) sits close to the outer edge, holding on to the metal bar, and is spinning around once every second, what is 7a) the centripetal acceleration? 7b) the force with which they have to gold on?
Humpback whales sometimes catch fishby swimming rapidly in a circle, blowing a curtain of bubbles thatconfuses a school of fish and traps it in a small area, where thewhales can easily catch and eat them. Suppose a 28,000-kg humpback whale swims at 2.2 m>s in a circle of radius 8.5 m. What centripetal force must the whale generate?
pls help me answer thank u In a test of "g"-suit, a volunteer is rotated in a horizontal circle of radius 6.3 m. What is the period of rotation at which the centripetal acceleration has a magnitude of a.) 2.5g b.) 10g?
There is a designed leg shaped machine to spin astronauts in a horizontal circle with a radius of 10 m. If the astronauts are to experience 5 g centripetal acceleration, how fast should they be moving?
A fairground ride spins its occupants inside a flying-saucer-shaped vehicle. If the horizontal circular path the riders follow has a radius of 7.5 m, at how many revolutions per minute will the riders be subjected to a centripetal acceleration 1.6 times that due to gravity?
