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.
