probability tree diagram vs area of a triangle using surds

Q.14 "A particle moves in a straight line. O is a fixed point on this line. The displacement of O from the particle in T seconds is S metres so that s= 2t^3-12t^2+7t. a) Find an expression for the velocity, v m/s, of the particle in t seconds. b) Find the time when the acceleration of the particle is instanteaneously zero." That's the whole question. What the actual fuck? I was expecting a maths question about some guy's back yard and pond or something. Not a physics question. And even then, how? I though differentiation would be for a) but then that didn't work for b) because the wording of the question implies that the acceleration only hits 0 once. Someone, try to explain this. I'm typically a very good person in maths but even this through me off. And the others who do better than me in tests couldn't figure this out. All 3 of us were stumped here. Any help would be appreciated.
