The answer is both.
For kinetic energy:
KE = 1/2*m*v^2 = 0.5*20,000 grams*5 = 50,000 J
For gravitational potential energy:
Pe = mgh = 20,000 grams*9.81 m/s^2*2 m = 392.2 J
Answer:
3.36m or 1680 N
Explanation:
Given:
Mass of the satellite =m
Mass of the moon Ganymede, M = 1.48 × 10²³ kg
Radius of Ganymede, R = 2631 km
Distance of satellite above the surface of the moon, d = 300 km
According to Universal Gravitational law:
where, G is the gravitational constant, M and m are mass of the objects and (R+d) is the distance between the centers of the objects.
Substitute the values:
If we consider mass of a satellite to be about 500 kg, the gravitational force between the moon and the satellite would be:
D: Velocity is decreasing. Acceleration is increasing.
A: Velocity is zero.
