Problem 58E

CALC? A system consists of two particles. At t = 0 one particle is at the origin; the other, which has a mass of 0.50 kg, is on the y -axis at y = 6.0 m. At t = 0 the center of mass of the system is on the y -axis at y = 2.4 m. The velocity of the center of mass is given by (a) Find the total mass of the system. (b) Find the acceleration of the center of mass at any time t. (c) Find the net external force acting on the system at t = 3.0 s.
