(a) Find ( v(t) ) (3 marks) (b) Find ( s(t) ) (2 marks)

(b) ( s(t) = \int (\sin 2t + \cos t) dt = -\frac12\cos 2t + \sin t + D ) ( s(0) = -\frac12(1) + 0 + D = -\frac12 + D = 0 \Rightarrow D = \frac12 ) [ s(t) = -\frac12\cos 2t + \sin t + \frac12 ] --- Integral Variable Acceleration Topic Assessment Answers
