A system cоnsists оf twо spheres, of mаss m аnd 2m, connected by а rod of negligible mass, as shown above. The system is held at its center of mass with the rod horizontal and released from rest near Earth's surface at time t = 0. A line graph has time t in seconds on the horizontal axis from 0 to 3 and the rate of change of linear momentum of a sphere of mass m on the vertical axis in newtons from 0 to 5. A horizontal line connects the points (0,5) and (3,5). The graph above shows the rate of change of linear momentum of the sphere of mass m as a function of time. What is the linear momentum of the two-sphere system at time t = 3.0 s?
