Answer:

impulse = 8820 kg·[tex]\frac{m}{s}[/tex] or 8820 N·s

Explanation:

Impulse J is equal to the average force [tex]F_{av}[/tex] multiplied by the elapsed time Δt or in equation form, J = [tex]F_{av}[/tex]Δt

As long as your force of 450 N is constant then that value is your average force [tex]F_{av}[/tex] and your elapsed time is 19.4 seconds.

Multiply these values.

You will get an impulse of 8820 kg·[tex]\frac{m}{s}[/tex] or 8820 N·s.
