By definition, the centripetal acceleration is given by:
Where,
v: tangential speed
r: radius of the circular path
Clearing the radio we have:
Substituting values we have:
Therefore, the radius of the circular path is equal to 0.60 meters.
Answer:
The radius of the circle is:
0.60 m
option1
To solve this problem it is necessary to take into account the concepts of Gravitational Force and Kinetic Energy.
The kinetic energy is given by the equation:
La energía gravitacional por,
Where m is the mass, v is the velocity, G the gravitational constant the mass of the earth, m the mass of the sun and d the distance ..
The sum of the energies, we must be a total energy
By the type of orbit we know that
E> 0 is a hyperbolic orbit
E = 0 is a parabolic orbit
E <0 is a closed orbit.
In the case of hyperbolic orbit
E>0
The case of the comet is a closed orbit, so,
E<0
For parabolic orbit
E=0
For the sun and the earth
where
For elliptical orbit
