A gymnast moves from a layout position to a tucked position during a flip - this will do whar to the rate of rotation.

the graph will serve as a refference in the question

A wheel of mass 40 kg and radius of gyration 0.5 m comes to rest from a speed of 180 rpm in 3s. Assuming that the ratardation is uniform then the value of retarding torque in Nm is-

Calculate the torque (Nm) about the center of a 14.4 kg hoop that is rotated at a constant angular acceleration of 0.9 rad/s2 if its radius is 0.42 m. Round off only on the final answer. Answer is expresses in 3 decimal places.

The ball has a mass of 1 kg and is confined to move along the smooth vertical slot due to the rotation of the smooth arm OA. The rod is rotating with a constant angular velocityd slot at any instant. Which one of the following is (are ) incorrect answers ? =2 rad/s. Assume the ball contacts only one side of the ion e-2 rads Select one or more: There is only one contact force on the ball that is acting perpendicular to the rod. There are two contact forces on the ball: one is acting perpendicular to the wall, and the other is perpendicular to the rod. The path of the ball is given by r 0.5 sec 0. The acceleration along the 0 increasing direction is a, tan 6 sec 00 The normal reaction to the ball by the rod is given by the equation N gcos+ a, whiere ap s the acceleration along the 6 increasing direction.

I neep help understanding how to solve for this question, could anyone help me out? Attachment for more details for the qiestion is given. Question:  Use the information in the given Table to show that it requires four times as much mass at half the distance from the center in order to produce the same moment of inertia. Assume a ruler's mass is negligible.

The rotational inertia of an object depends on  Group of answer choices the amount of torque applied to it. its color. how its mass is distributed about the spin axis. how fast it is spinning.

If the boy on the bicycle in the preceding problem accelerates from rest to a speed of 10.0 m/s in 10.0 s, what is the angular acceleration of the tires?

By keeping moment of invrtic of a body constant, if cue double the time period then angular momention of body. (@) remains constant (b) becomes halfs (Ⓒ) doubles (a) quadruples.

help pls asap not in scientific notation pls
