A torque of 0.97 N · m is applied to a bicycle wheel of radius 35 cm and mass 0.80 kg . You may want to review (Pages 339 - 341) . Part A Treating the wheel as a hoop, find its angular acceleration. Express your answer using two significant figures. ? keyboard shortcuts a = rad/s?

How do we do solve for formula ?

The 2.4 kg , 4.6-cm diameter disk is rotating as shown.

Dario, a prep cook at an Italian restaurant, spins a salad spinner and observes that it rotates with constant speed 20.0 times in 5.00 seconds and then stops spinning it. The salad spinner rotates 6.00 more times before it comes to rest. Assume that the spinner slows down with constant angular acceleration. Part A What is the magnitude of the angular acceleration of the salad spinner as it slows down? Express your answer numerically in radians per second per second. ▸ View Available Hint(s) a = 8.38 radians/s² Submit ✓ Correct Part B Previous Answers How long does it take for the salad spinner to come to rest?

Note: this problem does not require a kinematics table, as it does not involve the angular velocity changing at all. Both answers only require a single equation which you can find in your book. 3. The tire of a car has a radius of 0.26m. As the car travels down the street, the wheel spins with an angular velocity of w-80rad/s. a. How ow many times does the wheel spin per second? b. How fast is a point on the edge of the tire moving, in meters per second? (Incidentally, this is equal to the speed of the car as it drives down the road.)

A disk drive with a radius of 0.065 m starts rotating from rest with a constant angular acceleration. It takes 2.5 seconds to complete ten revolutions. One complete revolution takes how long? What is the linear displacement of the rim after ten revolutions? Determine the angular acceleration of the disk in radians per second squared (rad/s^2). Please provide work so I may better understand, thank you.

Part A A 5 N and a 10 N force act on an object. The moment arm of the 5 N force is 0.2 m. If the 10 N force produces five times the torque of the 5 N force, what is its moment arm? Express your answer in meters to one significant figure. ΙΠ ΑΣΦ Submit Request Answer ? m

Three forces are applied to a wheel of radius 0.350 m, as shown in the figure (Figure 1). One force is perpendicular to the rim, one is tangent to it, and the other one makes a 40.0° angle with the radius. Assume that F₁ = 12.3 N, F₂ = 14.2 N, and F3: 8.45 N. = Figure Part A 0.350 m 40.0° F F3 1 of 1 What is the magnitude of the net torque on the wheel due to these three forces for an axis perpendicular to the wheel and passing through its center?
