The escape velocity on Venus is 9761 m/s
Explanation:
The escape velocity from a planet is the speed that an object on the surface of that planet must have in order to completely escape the gravitational field of the planet.
Mathematically, it is calculated as

where
G is the gravitational constant
M is the mass of the planet
R is the radius of the planet
For Venus, we have:
is the mass
is the radius
Substituting, we find the escape velocity on Venus:

Explanation:
Answer:
A) 2.09
B) -62.09°
Explanation:
If D = A+B+C then C = D - A - B
Converting both A and B to rectangular coordinates, we get:
A = [-4.07 , 4.68] and B = [6.19 , 3.87]
Replacing these values we can get the x and y components of C:
C = [0.98 , -1.85]
Its module is:

Its angle is:
