a. if a particle's speed increases by a factor of three,bywhat factor does its kinetic energy change? b. particle A has half the mass and eight times thekineticenergy of particle B. what is the speed ratio va/vb? c. if a rotating skater triples her rate of rotationbydecreasing her moment of inertia by 1/3, by what factor doesherrotational kinetic energy change?
