Question

A wheel starts from rest and rotates with constant angular acceleration to reach an angular speed of 11.9 rad/s in 3.10 s. (a) Find the magnitude of the angular acceleration of the wheel.

Answer 1

The value is
`\alpha = 3.84 \ rad/s^2`

Step-by-step explanation:

From the question we are told that

The constant angular speed is
`w = 11.9 \ rad/s`

The time taken is
`t = 3.10 \ s`

Generally the magnitude of the angular acceleration is mathematically represented as

`\alpha = (w)/(t)`

=>
`\alpha = (11.9)/( 3.10 )`

=>
`\alpha = 3.84 \ rad/s^2`
