Answer: Value of impulse is \(2.4\times 10^3\text{kg m/s}\)
Explanation: lmpulse is defined as the amount of force acting over a short time interval 't' which is equal to the change in momentum of the body having mass 'm'.
Mathematically,
\(J=F\times t=m\Delta v\)
And,
\(\Delta v=v_2-v_1\)
Given:
\(m=1.2\times 10^3kg\\v_1=18m/s\\v_2=20m/s\)
Putting values in above equation, we get:
\(J=m(v_2-v_1)=1.2\times 10^3(20-18)\text{ kg m/s}\)
\(J=2.4\times 10^3\text{kg m/s}\)
