Review | Constants An experiment is performed in deep space with two uniform spheres, one with mass 21.0 kg and the other with mass 103.0 kg. They have equal radii, r = 0.20 m. The spheres are released from rest with their centers a distance 38.0 m apart. They accelerate toward each other because of their mutual gravitational attraction. You can ignore all gravitational forces other than that between the two spheres. Part A When their centers are a distance 26.0 m apart, find the speed of the 21.0 kg sphere. Express your answer in meters per second. ? Submit Request Answer m/s
