You’re driving down the highway late one night at 20 m/s. Given that your tire has a diameter of 65 cm, what is the angular speed of your tire?

Homework Answers

Answer #1

Let the angular speed is .

Given that the diameter of the tire is d=65 cm.

The linear speed v=20 m/s.

Let the radius of the tire is r.

The radius of the tire

  

  

Now we know the angular speed

  

The angular speed of the tire is 61.54 rad/s approximately.

Paul is driving south down Pembina highway at a constant speed of 20 m/s. He sees a truck in one of the north-bound lanes. The truck is initially stopped at the next traffic light, which is 500 m away. At this point, the light turns green and the truck starts accelerating northwards (towards Paul) at a constant acceleration of 1.2 m/s2. At what distance from the position where Paul first saw the truck, do they pass each other?
