Simply put on a pair of heavy boots, tie or tape a bottle of water to your foot, or place your cat on your foot as you GENTLY swing your foot from directly underneath you, to the extended position. 11. Which kinematic variables are similar and which are different between the two scenarios; moving your foot alone, and moving your foot with extra mass?12. Make a sketch of the angular acceleration of your foot (including the extra mass) as a function of time.During the experiment where you move your foot with the extra mass, you may have noticed that SOMETHING changed, though that may not have appeared on your graphs. You may not have a clear definition of what that SOMETHING is, but you certainly noticed that moving your foot was more difficult.
Please answer this within 30 minutes. I will upvote! The tub of a washing machine goes into its spin cycle, starting from rest and gaining angular speed steadily for 8.00 s, at which time it is turning at 5.00 rev/s. At this point, the lid of the washing machine is opened, and a safety switch turns it off. The tub then smoothly slows to rest in 16.0 s. Through how many revolutions does the tub rotate while it is in motion?

A solid, uniform disk of mass M and radius a may be rotated about any axis parallel to the disk axis, at variable distances from the center of the disk. (Figure 1) If you use this disk as a pendulum bob, what is T(d), the period of the pendulum, if the axis is a distance d from the center of mass of the disk? Express the period of the pendulum in terms of given variables. What is Tmin, the minimum period of the pendulum? Your answer for the minimum period should include given variables.
