Answer:
44.7 N
Explanation:
The gravitational force between the objects is given by:
where
G is the gravitational constant
m and M are the masses of the two objects
r is the distance between the centres of the two objects
In this problem, we have:
is the mass of the sphere
is the Earth's mass
is the Earth's radius, while h=310 km is the altitude of the sphere, so the distance of the sphere from Earth's centre is
Substituting into the equation, we find
Answer:
The time depends on the distance that they have to travel
Explanation:
The only horizontal force exerts over the car and you, it is the force that your friend is applied
Newton's Second Law of Motion defines the relationship between acceleration, force, and mass, thus
550 = 1430a
a = 0.3846 m/s2
The car and you have a motion under constant acceleration, then theirs position to a time-based is:
By the initial conditions
The time depends on the distance that they have to travel
