A constant force acting over the interval.
Impulse
20 N s
Momentum and Impulse Calculator
Change in momentum
20 kg m/s
Average force
10 N
Worked out from Newtonian mechanics: v = dx/dt, F = ma, J = F dt = dp, and the work-energy relations and 2 other sources.

How this is worked out

2 steps
  1. J = F dt = 10 x 2 = 20 N s
  2. By the impulse-momentum theorem, that impulse equals the change in momentum.
