Explanation:
In this case, law of conservation of energy will be implemented. It states that "the energy of the system remains conserved until or unless some external force act on it. Energy of the system may went through the conversion process like kinetic energy into potential and potential into kinetic energy.But their total always remain the same in conserved systems."
Given data:
Height of tower = 10.0 m
Depth of the pool = 3.00 cm
Mass of person = 61.0 kg
Solution:
Initial energy = Final energy
As the person was at height initially so it has the potential energy only.
Lets find out the magnitude of the force that the water is exerting on the diver.
W =ΔK.E
F = 1992.67 N
Let
M = the mass of the planet
n = the mass of the satellite.
r = the radius of the planet
When the satellite is at a distance r from the surface of the planet, the distance between the centers of the two masses is 2r.
The gravitational force between them is
where
G = the gravitational constant.
When the satellite is on the surface of the planet, the distance between the two masses is r.
The gravitational force between them is
