# A Ferris wheel of radius R speeds up with angular acceleration starting from rest. Find an expression for the (a) velocity and (b) centripetal acceleration of a rider after the Ferris wheel has rotated through angle .

a. The velocity of a rider after the Ferris wheel has rotated through angle is.

b. The centripetal acceleration of a rider after the Ferris wheel has rotated through angle is.

See the step by step solution

## Step 1: Given information

A Ferris wheel of radius speeds up with angular acceleration starting from rest. We have to find an expression for the (a) velocity and (b) centripetal acceleration of a rider after the Ferris wheel has rotated through angle .

## Part a) Step 1: Calculation

The formula is:

Where,

By putting values in formula:

## Part b) Step 1: Calculation

For centripetal acceleration:

Where,

Putting values in formula:
