Given the value of force applied in the given duration of time, the impulse or change in momentum caused by the net force is 720kgm/s.
An impulse is simply a concept that involves the change in the momentum of an object when force is introduced for a period of time.
It is expressed as;
ΔP or Change in Momentum = F × t
Where F is force applied and t is the elapsed time.
Given the data in the question;
ΔP = F × t
ΔP = 240kgm/s² × 3s
ΔP = 720kgm/s
Given the value of force applied in the given duration of time, the impulse or change in momentum caused by the net force is 720kgm/s.
