You pull on a string with a horizontal force of magnitude Fyb = 56 N that is attached to a block of mass m = 6 kg, then to the axle of a solid cylinder of mass me = 4.8 kg and radius r = 0.4 m, then to a spring of spring constant k = 60 N/m. This is all done on an inclined plane where there is friction (μs = 0.64 and μ = 0.38), and the incline angle is = 31 degrees. Everything starts at rest, and the spring is unstretched. The block slides down the plane, the cylinder rolls down the plane (without slipping), and the spring stretches. k belllllll b 0 Fyb

Diving from a high cliff, Cliff begins with a moderate rotational speed of a half rotation per second. Rank the following positions (and their moments of inertia) that cliff can assume during his dive, from the lowest rotational speed he will experience to the highest. + 1. Standing straight up, spinning about a head-to-toe axis: I = 0.3 kg m2 + 2. Bent in half, about an axis through his waist: I = 4 kg m- %3D + 3. Standing straight upwards, about an axis through his waist: I = 16 kg m2 + 4. Mass tucked inwards into a ball: I = 0.8 kg m- + 3. Arms out, spinning about a head-to-toe axis: I = 1.2 kg m2

Two wheels begin to spin at the same time. After 10 seconds, the second wheel is 1 rev ahead of the first. The angular acceleration of the first wheel 0,1 s -2 . Determine the angular acceleration of the second wheel. How many revolutions will each wheel make in 20 seconds? Find the angular velocity of each wheel at the end of the 20th second.

When installing a new MSA cylinder into the harness, slide it thru until the cylinder is resting near or on the bumpers. How far should we rotate the cylinder so the cylinder gauge is face up?

A disk, a hoop, and a solid sphere are released at the same time at the top of an inclined plane. They are all uniform and roll without slipping. In what order do they reach the bottom? sphere, hoop, disk O disk, hoop, sphere O sphere, disk, hoop O hoop, sphere, disk O hoop, disk, sphere

If a wheel, turning at a constant angular speed, makes ten complete revolutions every second, what is the angular speed, in radians per second?

For the system shown in the figure, the cylinder rolls without slipping. WWhat is the acceleration of mass M/4? R T M M/4 ICM=1/2 MR² g g/3 3g/4 2g/3 g/2

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.

What is the value of the angular acceleration of the second hand of the clock on the wall?

A compact disk (CD) in the computer rotates with a speed of 750 revolutions per minute A-express the angular speed of the CD IN THE unit of radian/ sec B- how long it takes for the CD to complete 7 revolutions
