Using the equation: f = μN 4 = μ(2)(10) μ = 0.2

Using the equation: ΔU = mgh ΔU = 5(10)(10) = 500 J Mechanics is a fundamental branch of physics that

Mechanics is a branch of physics that deals with the study of motion, forces, and energy. It is a fundamental area of physics that has numerous applications in various fields, including engineering, astronomy, and materials science. In Olympiads and contests, mechanics is a crucial topic that requires a deep understanding of concepts, formulas, and problem-solving strategies.

Using the conservation of momentum: m₁v₁ + m₂v₂ = m₁v'₁ + m₂v'₂ 2(5) + 0 = 2v'₁ + 3v'₂ Using the equation: f = μN 4 = μ(2)(10) μ = 0

A particle moves along a straight line with an initial velocity of 10 m/s. It accelerates uniformly at 2 m/s² for 5 seconds. Find the final velocity and displacement.

Using the kinematic equation: s = ut + (1/2)at² s = 10(5) + (1/2)(2)(5)² = 50 + 25 = 75 m Using the conservation of momentum: m₁v₁ + m₂v₂

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