How do you solve momentum problems?

ScanSolve AI Answer

Momentum p = mv (mass × velocity). In all collisions, total momentum is conserved: m₁v₁ + m₂v₂ = m₁v₁' + m₂v₂'. Elastic collisions: kinetic energy is also conserved. Inelastic: objects stick together, KE is lost. Example: 2kg ball moving at 5m/s hits a stationary 3kg ball (perfectly inelastic): (2)(5) + (3)(0) = (2+3)v → v = 10/5 = 2 m/s. Impulse = Δp = FΔt.
