Homework Statement
A 3.0-kg block is traveling to the right (the +x direction) at 5.0 m/s and a second 5.0-kg block is traveling to the right at 3.0 m/s.
1. Find the total kinetic energy of the two blocks, in Joules, to two significant digits.
2. Find the velocity of the center of mass of the two-block system, to one decimal place.
3. Find the velocity, including sign, of the first block relative to the center of mass, to one decimal place.
4. Find the velocity, including sign, of the second block relative to the center of mass, to one decimal place.
5. Find the kinetic energy of the blocks relative to the center of mass, in Joules, rounded to a whole number.
