Using the equation for elastic collisions: v'₁ = (m₁ - m₂)v₁ / (m₁ + m₂) v'₁ = (2 - 3)(5) / (2 + 3) = -1 m/s : Using the equation for elastic collisions: v'₁

Mechanics is a fundamental branch of physics that requires a deep understanding of concepts, formulas, and problem-solving strategies. By practicing problems and reviewing key concepts, you'll be well-prepared for Physics Olympiads and contests. Remember to stay focused, persistent, and patient, and you'll excel in this fascinating field. Using the equation: ΔU = mgh ΔU =

Using the equation: ΔU = mgh ΔU = 5(10)(10) = 500 J : Using the equation for elastic collisions: v'₁

Using the kinematic equation: v = u + at v = 10 + 2(5) = 20 m/s

v'₂ = 2v₁ / (m₁ + m₂) v'₂ = 2(5) / (2 + 3) = 2 m/s
