Solved: Figure 9-55 shows a two-ended "rocket" that is
Chapter , Problem 41(choose chapter or problem)
Figure 9-55 shows a two-ended "rocket" that is initially stationary on a frictionless floor, with its center at the origin of an x axis. The rocket consists of a central block C (of mass M = 6.00 kg) and blocks Land R (each of mass m = 2.00 kg) on the left and right sides. Small explosions can shoot either of the side blocks away from block C and along the x axis. Here is the sequence: (1) At time t = 0, block L is shot to the left with a speed of 3.00 mls relative to the velocity that the explosion gives the rest of the rocket. (2) Next, at time t = 0.80 s, block R is shot to the right with a speed of 3.00 mls relative to the velocity that block C then has. At t = 2.80 s, what are (a) the velocity of block C and (b) the position of its center?
