Impulse & Change of Momentum

A force acting for a time changes an object's momentum. The impulse J = FΔt equals the change in momentum Δp = m(v − u). Adjust the values and run it, or switch to a practice question.

Controls

Tasks
1. Calculate the change in momentum Δp.
2. Calculate the impulse J.
3. Calculate the average force F.

Practice question

Just give the size of each answer — a negative sign only shows direction, which you don't need here.
