landing. Which of the following actions would be most effective at rotating the bike counterclockwise, raising the front wheel relative to the rear?

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.

A wheel starts from rest and uniformly increases angular speed to 0.23 rev/s in 25 s.   (a) What is its angular acceleration in radians per second per second? _______rad/s2   (b) Would doubling the angular acceleration during the given period have doubled final angular speed? Yes or No

If you jump from a diving board and find that your body is rotating forward, you can spin your arms to stop the rotation and make your body land feet first. Explain in which direction you would rotate your arms and how this would help.

A flywheel of mass 186 kg has an effective radius of 0.620 m assume that the mass is concentrated along a circumference located at the effective radius of the flywheel What constant torque is required to bring the wheel from rest to an angular speed of 147 rev/min in a time interval of 30.0 s? answer in Nm

(a) What is the tangential acceleration of a bug on the rim of a 5.0 in. diameter disk if the disk moves from rest to an angular speed of 76 rev/min in 5.0 s? |m/s2 (b) When the disk is at its final speed, what is the tangential velocity of the bug? m/s (c) One second after the bug starts from rest, what is its tangential acceleration? ]m/s? What is its centripetal acceleration? m/s? What is its total acceleration? |m/s² ° (relative to the tangential acceleration)

The tires of a car make 85 revolutions as the car reduces its speed uniformly from 87.0 km/hkm/h to 58.0 km/hkm/h. The tires have a diameter of 0.82 mm. What was the angular acceleration of the tires? If the car continues to decelerate at this rate, how much more time is required for it to stop? If the car continues to decelerate at this rate, how far does it go? Find the total distance.
