a) A 95 kg astronaut stands on the surface of a spherical asteroid with a mass of 4.5 x 1015 kg and radius of 3.2 x 103 m. At what speed would he have to launch in order to escape the gravitational pull of the asteroid? Fully listing the steps on how you derive the formulas that you will be using.
b) What is the difference between escaping velocity and orbiting velocity?
An astronaut in deep space is at rest relative to a nearby space station. The astronaut needs to return to the space station. A student makes the following claim: “The astronaut should position her feet pointing away from the space station. Then, she should repeatedly move her feet in the opposite direction to each other. This action will propel the astronaut toward the space station.” Is the student’s claim correct? Justify your selection.
a
Yes. The astronaut’s feet will have a velocity that is transferred to her center of mass, accelerating the astronaut toward the space station.
b
No. The astronaut would move away from the space station, not toward it, since her feet are pointed away from the space station.
c
Yes. The astronaut’s feet exert a force away from the space station, creating an equal and opposite force that will accelerate the astronaut toward the space station.
d
No. The astronaut’s feet are not exerting a force on another object, so…

Suppose we have two particles named Particle Bea and Particle Binene. They both move in a
uniform gravitational field, which mean that they have a uniform acceleration due to gravity g. At time t = 0
Particles Bea and Binene were located at one point and moved with velocities vi = 7Vī m/s and v2 = 3*-1 m/s
horizontally in opposite directions. Find the distance between Particle Bea and Particle Binene at the moment
when their velocity vectors become mutually perpendicular.

Determine the gravitational force between them and their initial acceleration. Estimate how long it takes for them to drift together, and how fast they are moving upon impact. STRATEGY: Use Newton's law of gravitation to determine the force between them and then use Newton's second law to find the acceleration of each.
