A disk is free to rotate about an axis perpendicular to the disk through its center. If the disk starts from rest and accelerates uniformly at the rate of 3 radians/s2 for 4 s, its angular displacement during this time is.

The measure of the angles supplement is 30 more than four times that of its complement. find the measure of the angle described

Explain how you might determine the rate of weathering on a sample rock
