The rate at which a nebular cloud rotates increases as the cloud collapses to form systems of stars and planets. Consider a small segment of a nebular cloud with a mass m of 1.9 x 102" kg, tangential velocity vinitial equal to 6.8 km s-1 located at an orbital distance rinitial = 2.5 x 10* km. After the cloud collapses, the same small segment is located at an orbital distance rfinal = 3.2 x 10³ km. Calculate the change of the rotational velocity, Am, for the cloud segment, assuming perfectly circular orbits. Perform your work and report your solution using two significant figures.
