An astronaut, whose mission is to go where no one has gone before, lands on a spherical planet in a distant galaxy. As she stands on the surface of the planet, she releases a small rock from rest and finds that it takes the rock 0.480 s to fall 1.90 m. If the radius of the planet is 8.60 * 107 m, what is the mass of the planet?
What is the magnitude of angular momentum of JUST the partical circled to the system's mass center?
In 2014, the Rosetta space probe reached the comet Churyumov– Gerasimenko. Although the comet’s core is actually far from spherical, in this problem we’ll model it as a sphere with a mass of 1.0 x 1013 kg and a radius of 1.6 km. If a rock were dropped from a height of 1.0 m above the comet’s surface, how long would it take to hit the surface?
This time we have a non-rotating space station in the shape of a long thin uniform rod of mass 8.92 x 10^6 kg and length 867 meters. Small probes of mass 7618 kg are periodically launched in pairs from two points on the rod-shaped part of the station as shown, launching at a speed of 3581 m/s with respect to the launch points, which are each located 296 m from the center of the rod. After 17 pairs of probes have launched, how fast will the station be spinning? 2.35 rpm 6.10 rpm 1.88 rpm 4.69 rpm
A circular space station with a radius of 72 m has just been completed. In order to provide astronauts with the feeling of gravity, the space station will be set spinning about its central axis. To do this, solid fuel rockets have been attached around the perimeter of this station to start it spinning. These rockets fizzle out quickly, and produce a non-uniform angular acceleration of =a0e−bt Where a0 = 0.0424 rad/s2 and b = 0.153 s-1. The station is at rest (is not spinning) when the rockets are ignited at t = 0 s. What is the tangential speed of the outer edge of the station about the center of the station at t = 6.27 s? Through what angle has the station rotated in that time? Once the rockets are done burning, how long does it take the station to complete one revolution?
We have a non-rotating space station in the shape of a long thin uniform rod of mass 6.38 x 10^6 kg and length 605 meters. Small probes of mass 9511 kg are periodically launched in pairs from two points on the rod-shaped part of the station as shown, launching at a speed of 4412 m/s with respect to the launch points, which are each located 171 m from the center of the rod. After 20 pairs of probes have launched, how fast will the station be spinning? 7.88 rpm 14.08 rpm 11.26 rpm 22.53 rpm
A satellite is in an elliptical orbit, with a perigee of 2.0 earth radii and an apogee of 6.6 earth radii. If its velocity is 2.10 km/s at apogee, what is its velocity at perigee? Provide your answer in km/s. Hint: Make use of the conservation of angular momentum. A. 6.2 km/s B. 6.9 km/s C. 8.0 km/s D. 8.8 km/s
A nano-satellite has the shape of a disk of radius 0.30 m and mass 9.50 kg. The satellite has four navigation rockets equally spaced along its edge. Two navigation rockets on opposite sides of the disk fire in opposite directions to spin up the satellite from zero angular velocity to 9.0 radians/s in 17.5 seconds. If the rockets each exert their force tangent to the edge of the satellite (the angle theta between the force and the radial line is 90 degrees), what was is the force of EACH rocket, assuming they exert the same magnitude force on the satellite?
This time we have a non-rotating space station in the shape of a long thin uniform rod of mass 3.21 x 10^6 kg and length 1116 meters. Small probes of mass 6342 kg are periodically launched in pairs from two points on the rod-shaped part of the station as shown, launching at a speed of 2853 m/s with respect to the launch points, which are each located 370 m from the center of the rod. After 16 pairs of probes have launched, how fast will the station be spinning? a. 2.58 rpm b. 6.14 rpm c. 3.68 rpm d.8.60 rpm
Calculate the angular momentum of mass 15 kg in an elliptical orbit of dimensions10 cm and 20 cm about the mass 28 kg ?
Suppose a star the size of our Sun, but with mass 5.0 times as great, were rotating at a speed of 1.0 revolution every 10 days. If it were to undergo gravitational collapse to a neutron star of radius 14 km, losing three-quarters of its mass in the process, what would its rotation speed be? Assume also that the thrown- off mass carries off either. a) no angular momentum b) its proportional share three-quarters of the initial angular momentum
A satellite is in elliptical orbit with a period of 8.00 * 10^4 s about a planet of mass 7.00 * 1024 kg. At aphelion, at radius 4.5 * 10^7 m, the satellite’s angular speed is 7.158 * 10-5 rad/s.What is its angular speed at perihelion?
