Answer:
Asteroids
Explanation:
Asteroids are the small and large block of rocks that are found to be scattering space. There are numerous asteroids present in the asteroid belt which is located between the planet of Mars and Jupiter. These range from a few meters to hundreds of kilometers. They move so rapidly, at about 80,000 km/hr and there occurs constant collision with one another. These asteroids sometimes enter into the atmosphere of earth, which can cause a great mass extinction event.
These are believed to be the remnants particles that are present in space right after the formation of the solar system.
Answer:
a) centripetal force = m v^2 / R = 329 * (29.6 m/s)^2 / 183
F = 1580 Newtons
b) normal force = gravitational force - F = 329 * 9.8 - 1580 = 1640 N
