Kepler's laws follow which law discovered by Sir Isaac Newton?
2 answers:
Answer:
B. Universal Gravitational Law
Explanation:
As we know that Kepler gives three laws regarding the planetary motion of all planets around the sun
All his laws are derived from the basic Theory of law of attraction by gravitation.
Universal law of attraction given by Sir Issac Newton says that if two masses are placed at some distance from each other then the net force between two masses is given as
here we know that
= masses of two objects
= distance between two objects

Mass of the ball, m = 0.058 kg
Initial speed of the ball, u = 11 m/s
Final speed of the ball, v = -11 m/s (negative as it rebounds)
Time, t = 2.1 s
(a) Let F is the average force exerted on the wall. It is given by :
F = 0.607 N
(b) Area of wall,
Let P is the average pressure on that area. It is given by :
P = 0.202 Pa
Hence, this is the required solution.
