APFIVE Elastic Potential to Kinetic Energy
A block of mass m is placed against a spring with spring constant k, which is compressed a distance x from its equilibrium position. The block is then released from rest on a frictionless horizontal surface. What is the maximum speed the block attains?
A
v = x√(k/2m)
B
v = x√(2k/m)
C
v = x√(k/m)
D
v = x²√(k/2m)
