Velocity = displacement / time
Displacement = 2.3 km
Time = 5.78 mins
Velocity = 2.3/5.78
Velocity = 0.398 to the nearest 3 significant figures
Answer:
R=0.5B+0.5C+2A+D
Explanation:
By the triangular law of vector addition
vector R= vector B- vector D
As A,B,C,D are edges of the parallelogram,
A is parallel to D but opposite in direction.
Therefore
;
;

B is parallel to C and in same direction.



Answer:
18.4 m/s
Explanation:
The gravitational force between the Death Star and the Millenium Falcon is equal to the centripetal force that keeps the Millenium Falcon in circular orbit:

where
is the gravitational constant
is the mass of the planet
is the mass of the Millennium Falcon
is the orbital velocity of the Millennium Falcon
is the radius of the Death Star
is the altitude of the Millennium Falcon above the planet's surface
Solving the equation for v, we find the orbital velocity:
