Question

18-A tire rotates at a constant 1.7 radians angle every 0.15 s. A) What is the tire's angular 2 points
velocity? B) If the tire has a diameter of tire is 70 cm, what is the linear speed of the car?*

Answer 1

Explanation:

A) use the formula:

$angular \: velocity = angular \: dispacement \div time$

B) use the formula:

$linear \: velocity = radius \times angular \: velocity$

with angular velocity u calculated in A)
