Physics: centripetal acceleration and the gravitational force of an object?
radius of 1.54 × 10 ^ 11 m rotates on a star with a velocity of rotation of 1.48 × 10 ^ 6 m / s. The inhabitants of this world experience a ring of normal contact force ~ n. By themselves, the normal force produced to Inside acceleration 9.74 m / s ^ 2. Moreover, the center ring of the star exerts a gravitational pull on the ring of the gravitational constant inhabitants.The Universal is 6.67259 × 10.11 N • m2/kg2. What is the total centripetal acceleration of its inhabitants? Answer in units of m/s2. To determine the approximate mass star
Poorly worded question. I have to make some assumptions about meaning. First, and easiest, the centripetal acceleration. AC = v ^ 2 / r = 14.22 m / s ^ 2 seconds. Suppose that the ring itself has no serious gravity. The normal force is created entirely by the stars in the center. A.normal = A.star – a.star AC = AC a.normal + a.star = 9.74 m / s ^ 2 + 14.22 m / s ^ 2 a.star = 23.96 m / s ^ 2 Third Instead, find the mass of the star a.star = GM / r ^ 2 M r = a. star ^ 2 / g M = 8.52×10 ^ 33 kg
