Answer» HEYA!!! HERE IS YOUR ANSWER, >> GIVEN : Mass (m₁) = 35 KG. Mass (m₂) = 10 Kg, Initial Velocity (u₁) = 2 m/s, Initial Velocity (u₂) = -3 m/s and Final Velocity (v₁) = 0.75 m/s and Final Velocity (v₂) = ? >> SOLUTION : Applying Law Of CONSERVATION of Momentum, → m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂ → (35 × 2) + (10 × -3) = (35 × 0.75) + 10v₂ → v₂ = (70 - 30 - 26.3) ÷ 10 → v₂ = 1.4 m/s (EAST) >> THEREFORE, Final velocity (v₂) = 1.4 m/s (EAST) HOPE IT HELPS YOU, THANK YOU. |
