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?

Two manned satellites approaching one another at a relative speed of 0.550 m/s intend to dock. the first has a mass of 2.50 ✕ 103 kg, and the second a mass of 7.50 ✕ 103 kg. assume that the positive direction is directed from the second satellite towards the first satellite. (a) calculate the final velocity after docking, in the frame of reference in which the first satellite was originally at rest.(b) what is the loss of kinetic energy in this inelastic collision? (c) repeat both parts, in the frame of reference in which the second satellite was originally at rest. final velocity(d) loss of kinetic energy = ?
