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

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.
