Question

A large cylinder rolls along flat, level ground. Because of substantial air resistance and varying amounts of friction, its speed decreases in a complicated way. Its speed as a function of time is v = at2 + bt + c, where v is measured in m/s, t is never negative and is measured in s, a = - 2.00 m/s3, b = - 2.00 m/s2, and c = 12.0 m/s. How far does the cylinder move (in meters) from t = 0 s until it comes to rest? For the physical representation (part 2a), draw an accurate and complete graph of speed vs. time.
