The Figure Shows A Two Ended Rocket That Is Initially Stationary On A Frictionless Floor With Its Center At The Origi 1 (114.11 KiB) Viewed 32 times

The figure 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 = 7.20 kg) and blocks L and R (each of mass m = 2.40 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 Lis shot to the left with a speed of 3.40 m/s 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 3.40 m/s relative to the velocity that block C then has (after the second explosion). At t = 3.50 s, what are (a) the velocity of block C (including sign) and (b) the position of its center? (a) Number i (b) Number i Units Units 0
