Q1. Presume your local government wants to raise your taxes in order to support the construction of wind and solar power plants that can give your town with low-polluting energy and help decrease your town's dependence on fossil fuels for energy. Would you support a tax increase for this purpose? Describe why or why not.
Q2. A two-ended "rocket" that is at first stationary on a frictionless floor, with its center a origin of an x axis. The rocket consists of a central block C (of mass M = 5.00 kg) and blocks L and R (each of mass m = 1.00kg) on the left and right sides. Small explosions can shoot either of the side blocks away from mblock 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 2.70 m/s relative to the velocity that the explosion gives the rest of the rocket. (2) Next at the time t = 0.60s, block R is shot to the right with a speed of 2.70 m/s relative to velocity that block C then has. At t = 2.60 s, what are the (a) velocity of block C and (b) position of its center?
