An object's velocity after t seconds is v(t)=322t\displaystyle {v}{\left({t}\right)}={32}-{2}{t} feet per second.

(a) How many seconds does it take for the object to come to a stop (velocity = 0)?
  seconds

(b) How far does the car travel during that time?
  feet

(c) How many seconds does it take the car to travel half the distance in part (b)?
  seconds
