Answer:
16 Newton-seconds
Explanation:
Impulse, [tex]\widehat{J}[/tex], is given by [tex]\widehat{J}=F\Delta t[/tex], where [tex]F[/tex] is the magnitude of a force that has been applied for [tex]\Delta t[/tex] seconds.
Given [tex]F=80\text{ N}[/tex] and [tex]\Delta t = 0.2\text{ s}[/tex], we have:
[tex]\widehat{J}=80 \cdot 0.2 = \boxed{16\text{ Ns}}[/tex]
