A particle of mass m1 accelerates at 4.50 m/s2 when a force F is applied. A second particle of mass m2 experiences an acceleration of only 1.35 m/s2 under the influence of this same force F.
(a) What is the ratio of m1 to
m2?
(b) If the two particles are combined into one particle with
mass
m1 + m2, what is the acceleration of this particle under the influence of this force F?

Two particles are moving along the x axis. Particle 1 has a mass m1 and a velocity v1 = +4.5 m/s. Particle 2 has a mass m2 and a velocity v2 = -7.3 m/s. The velocity of the center of mass of these two particles is zero. In other words, the center of mass of the particles remains stationary, even though each particle is moving. Find the ratio m1/m2 of the masses of the particles.
