O 22.2 m/s Question 11 1 pts A 9.3x10 2 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 270 N/m . The block is pulled from its equilibrium position at x = 0 m to a displacement x - +0.080 m and is released from rest. The block then executes simple harmonic motion along the x-axis (horizontal). The maximum elastic potential energy of the system is closest to: O 1.2 J O 1.0 J 1.5 J O 0.86 J O 0.61 J Question 12 1 pts A mass m = 8 kg is attached to a spring and allowed to hang in the Earth's gravitational field.

The spring stretches 4.4 cm before it reaches its equilibrium position. If allowed to oscillate, what would be its frequency? 3.6 x 10 Hz O 4.8 Hz O 1.2 Hz O 2.4 Hz Question 13 1 pts String is wrapped around the outer rim of a solid uniform cylinder that is free to rotate about a frictionless axle through its center. When the string is pulled with a force P tangent to the rim, it gives the cylinder an angular acceleration a. If the cylinder II app.honorlock.com is sharing your screen.
