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.
