Dario, a prep cook at an Italian restaurant, spins a salad spinner 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. What is the angular acceleration of the salad spinner as it slows down? Express your answer numerically in radians per second per second.ω = θ / t ω = 20 * 2 * π / 5.00 ω = 8π ω = 25.13272 radians/s now I can solve for α using a kinematic equation: ω2f = ω20 + 2α(θ) 02 = 25.132722 + 2 * α * (2 * π * 6.00) 0 = 631.6536 + 75.39816α 75.39816α = -631.6536 α = -8.37757 radians/s2

Sagot :

The angular acceleration, which is frequently denoted by the symbol and stated in radians per second per second, is the rate at which the angular velocity changes over time. = t and = 0 for the scenario when the angular velocity is constant (nonvarying).

In layman's words, what is angular acceleration?

A spinning object's change in angular velocity per unit of time is expressed quantitatively as angular acceleration, also known as rotational acceleration. It is a vector quantity with either one of two predetermined directions or senses and a magnitude component.

What is the basic angular acceleration formula?

The rate at which angular velocity changes is referred to as angular acceleration. Angular acceleration is written as the equation: =t = t, where is the change in angular velocity and t is the change in time.
