force plate analysis but I'm not sure which of Newton’s laws of motion is employed in a force plate analysis?

A 5kg lacrosse stick has a moment of inertia about a transverse axis through its center of gravity of 8 kg.m2. When a player swings the stick at an opponent, the axis of rotation is through the end of stick, 80 cm from the center of gravity of the stick. What is the moment of inertia relative to this swing axis? A 4 kg lacrosse stick has a radius of gyration of 60cm about a transverse axis through its center of gravity. When a player swings the stick at an opponent, the axis of rotation is through the end of stick, 120cm from the center of gravity of the stick. What is the moment of inertia relative to this swing axis?

A solid spare, a solid disk, and a thin hoop are all released from rest at the top of the incline (ho = 20.0 cm).  a) without doing any calculations, decide which object would be spinning the fastest when it gets to the bottom. (Explain) b) again, without doing any calculations, decide which object would get to the bottom first. (Which one has greater translational speed?) think CoE. c) assuming all objects are rolling without slipping, have a mass of 2.00 kg and a radius of 3.00 cm, find the rotational and translational speed at the bottom of the incline of any one of these three objects.

4. A rod of length L, = 1.50 m moves along the horizontal direction. The rod makes an angle 0, = 25.0° with the x' axis of its own moving reference frame S'. (a) How fast will the rod need to be traveling relative to an observer at rest to measure and angle of e = 71.0° with the axis x of the rest reference frame S? (b) If the rod has a mass of 1.00 kg, then how much work would have been done to accelerate the rod to this speed from an initial speed of 1.00 x 105 m/s?
