Gravitational force between sun and planet is given by,
Thus, The force of gravitation is inversely proportional to the distance.
Kepler's law states that the square of period of planet is proportional to cube of semi major axis of its orbit.
The time period of planet is more when the gravitational force is less.
Thus, planet Y is closer to earth because sun exert greater gravitational force than planet Z.
Answer: The time of contact will be 0.006 seconds.
Explanation:
An impulse of a force is the product of average force and the time interval when the force acts.
Mathematically,
Where,
J = impulse = 3.6 Ns
F = Force = 600N
= Time = ?s
Putting the values in above equation, we get:
t = 0.006 seconds
Hence, the time of contact will be 0.006 seconds.
