2. Use the grids below to draw the following harmonic motion graphs. Be sure to label the y-axis to indicate the measurement scale.
A pendulum with an amplitude of 2 cm and a period of 1 second.

Adiver in midair has an angular velocity of 6.0 rad/s and a moment of inertia of 1.2 kg·m2. he then pulls is arms and legs into a tuck position and his angular velocity increases to 12 rad/s. the net external torque acting on the diver is zero. what is his moment of inertia in the tuck position?

Suppose while hauling rocks, you accidentally drop one. it breaks apart in flat, planar sections. what type of rock did you just drop? 20 points
