Particle A has half the mass and eight times the kinetic energy of particle B. What is the speed ratio VA/VB?
i cant figure this out for the life of me and i know it is easy If the masses are m[a], m[b], the kinetic energies are K[a], K[b], and the speeds are v[a], v[b] then: K[a] = m[a] v[a]^2 / 2 …(1) K[b] = m[b] v[b]^2 / 2 …(2) Dividing (2) by (1): (v[a] / […]
