A spaceship of mass 110 kg is going to use a planet for a gravitational assist - that is, use the planet's gravity to change its direction of travel without expending any fuel. It is initially moving at a velocity of 230 m/s and at an angle of φ0 = 65°, at a distance 10200 km from the center of the planet as shown in the figure. Give an expression for the angular momentum of the spacecraft, using the coordinate system specified, in terms of m, r0, v0, φ0, and unit vectors i, j, and k. If the spaceship whips around the planet to the other side so that the angle is φ = 45° and is moving at 105 m/s, how far, in kilometers, from the planet is it?

A space station has the form of a hoop of radius R = 13 m, with mass M = 7000 kg. Initially its center of mass is not moving, but it is spinning slowly with angular speed ω0 = 0.0016 radians/s. Then a small package of mass m = 5 kg is thrown by a spring-loaded gun toward a nearby spacecraft at an angle of θ = 22° as shown; the package has a speed v = 37 m/s after launch.Calculate the center-of-mass velocity of the space station and its rotational velocity after the launch in vector form.
A merry-go-round is a playground ride that consists of a large disk mounted to that it can freely rotate in a horizontal plane. The merry-go-round shown is initially at rest, has a radius R = 1.1 meters, and a mass M = 246 kg. A small boy of mass m = 46 kg runs tangentially to the merry-go-round at a speed of v = 1.9 m/s, and jumps on. 1.The boy then crawls to the center of the merry-go-round. What is the angular speed in radians/second of the merry-go-round when the boy is at the center of the merry go round? 2.Finally, the boy decides that he has had enough fun. He decides to crawl to the outer edge of the merry-go-round and jump off. Somehow, he manages to jump in such a way that he hits the ground with zero velocity with respect to the ground. What is the angular speed in radians/second of the merry-go-round after the boy jumps off?
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?

Now let's apply our definition of angular momentum to a specific object. A mobile sculpture is suspended from the ceiling of an airport terminal building. It consists of two metal spheres, each with mass 2.0 kg, connected by a uniform metal rod with mass 3.0 kg and length s=4.0ms=4.0m. The assembly is suspended at its midpoint by a wire and rotates in a horizontal plane, making 3.0 revolutions per minute.
