Question 1
A car has tires of outer diameter 600 mm. The car can achieve a speed of 120
km h in 15.7 seconds while accelerating from rest with a constant acceleration.
a) What is the angular acceleration of the tires during acceleration?
b) Find the angular speed of the tires 5.0 seconds after the car started to move?
c) What was the angular speed, frequency and the period of rotational motion at the
end of the acceleration?
d) What was the tangential speed of a particle on the outer rim of the tyre 3.0 s after
start?
Question 2
How many revolutions do the tires make while accelerating the car? Solve this by finding
out the total angular displacement of the tyre, and dividing this by the amount of angular
displacement corresponding to one full revolution.
Question 3
A compact disk of diameter 120 mm is rotating at 380 rpm. Find the tangential
velocity and the total acceleration of a byte located at a radial distance of
a) 10 mm,
b) 55 mm from the axis of rotation.

Charles, Collen is right do you own homework, you will glad some day that you did!
They are simply multiplication problems, do your homework if you ever expect to get good job the will provide you a decent income.
I was born a poor black boy in souther Georgia in 1926. I worked hard to learn, in a rotten schools.
By the time I was twenty i was attending one of the finest Engineer Schools, at a well known norther University.
By the time I was 35 I had worked for Chrysler and GM. When I was 50 I retired from my job as a Design Engineer for Ford.
When I was 55 I started my Automobile Fleet Service Business, servicing the vehicles of large and small Federal, State and local governments, as well as large and small Corporations
It grew from one shop in Pennsylvania, to 26 shops in six eastern states. I sold my business and retired at age 73 as a multimillionaire
It began for me as a little boy, when my Mom made me read all types of books that she got from the library. she taught me that learning to read was the most important thing in life. I could lean anything I wanted, from books. Today you can do it on the Internet.
