The velocity of an object with a mass of 4 kg is given by v(t)= sin 9 t + cos 3 t . What is the impulse applied to the object at t= pi /3 ?

This question is utterly wrong. Unfortunately I see so many of these that ask about the impulse at a particular instant. Impulse is defined for a time-interval and not for an instant of time.
