Question 1
A 0.39-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is
The block is pulled from its equilibrium position at
x = 0.000 m to a displacement
x = +0.080 m and is released from rest. The block then executes simple harmonic motion along the horizontal
x-axis. When the position of the block is
its kinetic energy is closest to
◦ 1.0 J.
◦ 1.1 J.
◦ 0.95 J.
◦ 0.84 J.
◦ 0.90 J.
Question 2
A 3.7-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is
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
◦ 1.7 J.
◦ 1.6 J.
◦ 1.8 J.
◦ 1.3 J.
◦ 1.4 J.
