Adisc initially at rest experiences an angular acceleration of 3.11 rad/s for a time of 15.0 s. what will the angular speed of the disc be at this time, in units of rad/s?

The angular speed of the disc be at this time is 46.65 rad/s.

Explanation:

Given that,

Angular acceleration

Time t =15.0 s

We will calculate the angular speed of the disc

A disc initially at rest.

So,

Using rotational kinematics equation

Where, = initial angular speed

=final angular speed

= angular acceleration

Put the value in the equation

Hence, The angular speed of the disc be at this time is 46.65 rad/s.

get the total number of pieces of fruit and divide it by 4 to get the average. the result is the answer to the problem. 14 total number of fruits and there are 4 members. 14 divided by 4 is equals to 3.5.
