2. A 1.00-kg block compresses a spring for which k1 = 100. N/m by 20.0 cm and is then released to move across a horizontal, frictionless table, where it hits and compresses another spring, for which k2 = 50.0 N/m. Determine
the total mechanical energy of the system,
the speed of the mass while moving freely between springs, and
the maximum compression of the second spring.
In one design, the large spring with spring constant 2.0×10^4 was placed behind the cannon. The other end of the spring braced against a post that was firmly anchored to the ship's frame.
