Here are some examples of physics problems with solutions in mechanics:
:
Using the conservation of momentum: m₁v₁ + m₂v₂ = m₁v'₁ + m₂v'₂ 2(5) + 0 = 2v'₁ + 3v'₂
Using the kinematic equation: s = ut + (1/2)at² s = 10(5) + (1/2)(2)(5)² = 50 + 25 = 75 m : Here are some examples of physics problems

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