Atruck with 28-in.-diameter wheels is traveling at 50 mi/h. find the angular speed of the wheels in rad/min, *hint convert miles to inches & hours to minutes: rad/min how many revolutions per minute do the wheels make? rpm

Angular speed ω=3771.4 rad/min

Revolution=5921 rpm

Explanation:

Given data

To find

Angular speed ω

Revolution per minute N

Solution

First we need to convert the speed of truck to inches per mile

as

1 mile=63360 inches

1 hour=60 minutes

so

Now to solve for angular speed ω by substituting the speed v and radius r in below equation

To solve for N(revolutions per minute) by substituting the angular speed ω in the following equation
