The backward impulse stops the cart.

Impulse changes momentum

A force of 100 N acting for 0.10 s gives an impulse of 10 N·s.

Blue = momentum

Red = impulse

J = F × Δt = Δp

Equations and live calculation

Momentum: p = m × vMass multiplied by velocity.10.0 = 2.0 × 5.0 kg·m/s

Impulse: J = F × ΔtAverage force multiplied by contact time.−10.0 = −100 × 0.10 N·s

Impulse–momentum theorem: J = Δp = p₂ − p₁Impulse equals the change in momentum.−10.0 = 0.0 − 10.0 kg·m/s

Final velocity: v₂ = p₂ ÷ mFinal momentum divided by mass.0.0 = 0.0 ÷ 2.0 m/s

p = momentum, m = mass, v = velocity, J = impulse, F = average force, Δt = contact time.
