angular acceleration w

What is the final velocity (in m/s) of a hoop that rolls without slipping down a 6.50-m-high hill, starting from rest? m/s

I need help in this please

E7. Starting from rest, a merry-go-round accelerates at a con- stant rate of 0.2 rev/s2. a. What is its rotational velocity after 5 s? b. How many revolutions occur during this time?

A. 307 rad/s B. 167 rad/s C. 367 rad/s

Define angular velocity.

Answer Question 5: 5. The merry-go-round above slows down and comes to a stop in Δt = 6.00 s. What is the average angular acceleration during this time?

The turntable on a record player slows from 5.0 nd to nd 7.3- turntable's angular acceleration? in 3.1 s. What is the nd 4.0 2.1분 rad -7.1 rad D. rad -0.74 B.

When a fan is turned off, its angular speed decreases from 168 rpm to 64.0 rpm in 6.08 s. A) what is the angukar acceleration of the fan? B) How fast the edges of the blades are moving (in m/s) at time 6.08 s, if they are 86.0 cm long?

Physics sample problems about vectors. Thought I knew how to do them but keep getting wrong answers.

7. How many rpm would a Ferris wheel need to make for a person to feel weightless at the top of the rideif the wheel has a diameter of 16.5m?

a shower if JU equivalent situation, a rolle FIGURE 8.14 Shows a roller-coaster car gu radius r. Why doesn't the car fall off at the top of the circle eircle is not uniform circular motion; the car slows down as it goes up one and speeds up as it comes back down the other. But at the very top tom points, only the car's direction is changing, not its speed, so at those points the acceleration is purely centripetal. Thus there must be a net force toward the center The aus poats toward abe center and very bot- motion, so the water trajectory toward yo of the circle. 8-8 CHAPTER 8 Dynamics II: Motion in a Plane 15. It's been proposed that future space stations create "artificial gravity" by rotating around an axis. a. How would this work? Explain. b. Would the artificial gravity be equally effective throughout the space station? If not, where in space station would the residents want to live and work?

two disks with radii R and 3R are connected by a rubber belt which doesn’t slip on the surface of each disk. if the small disk rotates with an angular velocity, what is the angular velocity of the larger disk?
