Question

A flywheel with radius of 0.300 m starts from rest and accelerates with a constant angular acceleration of 0.400 rad/s2.For a point on the rim of the flywheel, what is the magnitude of the tangential acceleration after 2.00 s of acceleration

Answer 1

`0.12\ m/s^2`

Step-by-step explanation:

Given that,

The radius of a flywheel, r = 0.3 m

Angular acceleration of a flywheel,
`\alpha =0.4\ rad/s^2`

We need to find the magnitude of the tangential acceleration after 2.00 s of acceleration.

The relation between the tangential and angular acceleration is given by :

`a_t=r\alpha \\\\a_t=0.3* 0.4\\\\a_t=0.12\ m/s^2`

So, the required magnitude of tangential acceleration is
`0.12\ m/s^2`.
