Question

A Car has tires that are one meter in diameter. The tires are turning at 100rpm. What angle does a tire move through after 3 seconds? EXPLAIN HOW TO PLEASE

Answer 1

100rpm = 100/60rps
2pi (100) rad per min = 2pi (100/60) rad per sec

Answer 2

I need to know the angle - NOT angular velocity

Answer 3

How can you use that to find the angle

Answer 4

Well, isnt there a way to set a proportion to find the angle

Answer 5

If you know 2pi (100/60) rad per sec, what can you do if you know it travels for 3 seconds?

Answer 6

multiply by 3?

Answer 7

yes!

Answer 8

So I tried setting this up:

Answer 9

okay..
