Answer:
t = 1.09 s.
Explanation:
This is a one-dimensional kinematics question, so the equations of kinematics will be sufficient to solve the question.
This quadratic equation can be solved using determinant.
Of course, we will choose the positive time.

Answer:
The gravitational force between two objects, one of mass M1 and the other of mass M2, is:
F = G*M1*M2/R^2
Where G is a constant:
G = 6.6x10^11 m^3*/(kg*s^2)
And R is the distance between the two objects.
M1 = 5.9742x10^24 kg
M2 = 7.36x10^22 kg
R = 382171 km = 382171000 m
Then the gravitational force is:
F = 6.6x10^-11 m^3*/(kg*s^2)*(5.9742x10^24 kg)*(7.36x10^22 kg)/(382171000 m)^2
F = 1.987x10^20 N
