Abody rotates around a self-contained axis once every 58 days. it also revolves around
an external point, 58 million kilometers away every 88 days. it has a mass of 3.3x1023
kilograms.
a. what is the centripetal force acting on this object in newtons?
b. the object changes its rotational period from once every 58 days to once every
34 days over 7 years. what is the angular acceleration during this time in rad/s2?
c. using your response from part b, how many complete rotations will the object
make over those 7 years?
