Title: A 0.23 kg block on a horizontal frictionless surface is attached to a spring Post by: mikael on May 14, 2014 A 0.23 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 470 N/m. The block is pulled from its equilibrium position at x = 0m to a displacement x = +0.080m and is released from rest. The block then executes simple harmonic motion along the x-axis (horizontal). When the displacement is x = 0.021 m, the kinetic energy of the block is closest to: A) 1.4 J B) 1.3 J C) 1.5 J D) 1.6 J E) 1.7 J Title: Re: A 0.23 kg block on a horizontal frictionless surface is attached to a spring Post by: padre on Jun 18, 2014 Content hidden
