TRUE OR FALSE: Kinematic equations can be used in conjunction with this graph. Give a brief reason to support your answer.
What is false? (Because acceleration isn't constant)

The differential equation used to solve for the velocity as a function of time for an object that falls through the air with a resistive force of magnitude bv.
What is
mg - bv = m(dv)/dt

A glob of clay (mass m) falls down through the air and sticks to the edge of a uniform disk (mass M, radius R). If the disk is pivoted about its center and the clay was moving with speed v just before it hit the disk, this is the resulting angular velocity of the clay-disk system.
What is
