Answer:
\[m=250\,\,g=0.25\,\,kg\]
\[v=20m/s\]
\[t=0.01s\]
impulse \[(I)=?\]
\[I=F\times t\] ………. (1)
But \[F=ma\] ………. (2)
Now \[a=\frac{V}{t}=\frac{20}{0.01a}m/{{s}^{2}}=2000m/{{s}^{2}}\]
Substituting the above value in (2), we get
\[F=0.25\times 2000=500N\]
Substituting the above value in (1), we get
\[\therefore I=F\times t=500N\times 0.01s=5\,\,Ns\]
