Question

The impulse (J) delivered during a collision is given by:

Options

• J = m₁u₁ + m₂u₂

• J = μ(1 + e)uᵣₑₗₐₜᵢᵥₑ

• J = (m₁ + m₂)v

• J = Δ(K.E.)

Answer 1

J = μ(1 + e)uᵣₑₗₐₜᵢᵥₑ

Explanation:

The magnitude of impulse is J = μ(1 + e)uᵣₑₗₐₜᵢᵥₑ, where μ is reduced mass, e is coefficient of restitution, and uᵣₑₗₐₜᵢᵥₑ is the relative velocity of approach.
