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?

A circular saw blade 0.170 m in diameter starts from rest In 8.00 s it reaches an angular velocity of 170 rad/s with constant angular acceleration For related problem-solving tips and strategies, you may want to view a Video Tutor Solution of Rotation of a bicycle whheel.
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.)
Using the equations attached solve the following: 1.What is the average angular velocity between t = 2.0 s and t=3.1 s ? Express your answer using two significant figures. 2.What is the average angular acceleration between t = 2.0 s and t =3.1 s ? Express your answer using two significant figures.

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?
