Two Blocks#

Two blocks, \(M =\) 2\(m\), sit on a horizontal frictionless surface with a compressed massless spring between them. After the spring is released \(M\) has velocity \(v\).

A spring connects a block of mass m to its left to a block of mass M to its right

Part 1#

What was the total energy initially stored in the spring?

Answer Section#

  • 3.0 \(mv^2\)

  • 4.0 \(mv^2\)

  • 8.0 \(mv^2\)

  • 20.0 \(mv^2\)

  • 6.0 \(mv^2\)
