Question

. Two identical vehicles traveling at the same speed are made to collide with barriers in an insurance company collision test. The first vehicle collides with a concrete barrier, and stops in a time of approximately 0.1 s. The second vehicle collides with a collapsible barrier, and comes to rest in about 1 second. Which object is subject to a larger force

    Answer:

    F₁ / F₂ = 10

    therefore the first out is 10 times greater than the second barrier

    Explanation:

    For this exercise let’s use the relationship between momentum and momentum.

             I = F t = Δp

    in this case the final velocity is zero

            F t = 0 -m v₀

            F = m v₀ / t

    in order to answer the question we must assume that the two vehicles have the same mass and speed

    concrete barrier

            F₁ = -p₀ / 0.1

            F₁ = – 10 p₀

    barrier collapses

             F₂ = -p₀ / 1

    let’s look for the relationship of the forces

            F₁ / F₂ = 10

    therefore the first out is 10 times greater than the second barrier
