A 37-Kg Block on a Horizontal Frictionless Surface Is Attached to to an Ideal

question 41

Multiple Choice

A 3.7-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is 450 N/m. The block is pulled from its equilibrium position at x=0.000 m to a position x=+0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal x -axis. The maximum elastic potential energy of the system is closest to

• A) 1.8 J
• B) 1.7 J
• C) 1.4 J
• D) 1.3 J
• E) 1.6 J
