## Homework Statement

Starting from rest, a ferris wheel of diameter 30.0m undergoes an angular acceleration of 0.040 rad/s^2. A certain rider is at the lowest point of the wheel just as it starts to move.

a)find the velocity of the rider just as he completes a quarter of a turn.

b)find the radial and tangential components of his acceleration at the same point.

c)how much farther must the wheel turn before the rider attains a speed of 6.00m/s(the maximum that occurs during the ride)?

## Homework Equations

v = ωr

what other equations?

## The Attempt at a Solution

circumference of ferris wheel is 94.2m and a quarter of that is 23.56m. 2pi is a circle and a quarter of that is pi/2. I have no idea how to do this. the answers from the back are

a)5.32m/s up

b)0.600m/s^2up and 1.88m/s^2 toward center

c)24.6 degrees
