Answer:
The time taken is 6.7 min
Explanation:
Using the linear momentum conservation theorem, we have:
when she was 60.4m from the shuttle, she has zero speed, so the initial velocity is zero.
That is 0.15m/s in the opposite direction of the camera.
the time taken to get to the shuttle is given by:
A) 8.11 m/s
For a satellite orbiting around an asteroid, the centripetal force is provided by the gravitational attraction between the satellite and the asteroid:
where
m is the satellite's mass
v is the speed
R is the radius of the asteroide
h is the altitude of the satellite
G is the gravitational constant
M is the mass of the asteroid
Solving the equation for v, we find
where:
Substituting into the formula,
B) 11.47 m/s
The escape speed of an object from the surface of a planet/asteroid is given by
where:
Substituting into the formula, we find:
