Impulse is defined by : 

                                                 I\ =\ mv\ -\ mu                                 (Change in momentum).

At   t = 0 s :

                                                 u\ =\ 0\ and\ v\ =\ \frac{3}{4}\ m/s

or                                               I\ =\ 4(\frac{3}{4})\ -\ 0

or                                               I\ =\ 3\ Kg\ m/s

At   t  = 4 s  : 

                                                 u\ =\ \frac{3}{4}\ m/s                  and                  \ v\ =\ 0

Thus                                           I\ =\ 0\ -\ 4\left ( \frac{3}{4} \right )

or                                                I\ =\ -3\ Kg\ m/s
