PhysicsEasy65×since 2002Q7884The position of a particle as a function of time t, is given by x(t) = at + bt² – ct³ where a, b and c are constants. When the particle attains zero acceleration, then its velocity will be :Aa+b2ca + {{{b^2}} \over {c}}a+cb2Ba+b24ca + {{{b^2}} \over {4c}}a+4cb2Ca+b23ca + {{{b^2}} \over {3c}}a+3cb2Da+b22ca + {{{b^2}} \over {2c}}a+2cb2Check answerSkip
