The Figure Shows A Two Ended Rocket That Is Initially Stationary On A Frictionless Floor With Its Center At The Origi 1 (34.37 KiB) Viewed 35 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-7.90 kg) and blocks Land R (each of mass m-2.10 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 3.20 m/s relative to the velocity that the explosion gives the rest of the rocket. (2) Next, at time t-0.70s, block R is shot to the right with a speed of 3,20 m/s relative to the velocity that block C then has (after the second explosion). Att - 3.20s, what are (a) the velocity of block C (including sign) and (b) the position of its center? (a) Number (b) Number Units Units m/s m
