- 8. Multiple ChoiceA 4.8-kg block attached to an ideal spring executes simple harmonic motion on a frictionless horizontal surface. At time t = 0.00 s, the block has a displacement of -0.90 m, a velocity of -0.80 m/s, and an acceleration of +2.9 m/s/s. The force constant (spring constant) of the spring is closest to15 N/m.14 N/m.13 N/m12 N/m.
- 9. Multiple ChoiceA 0.39-kg block on a horizontal frictionless surface is attached to an ideal spring whose force constant (spring constant) is 570 N/m. 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 x=0.057 m its kinetic energy is closest to0.90 J.0.84 J.0.95 J.1.0 J
