Homework Statement
Car runs at 55 mi/hr. and the nail is lodged in tire 13 in from center of wheel, then what is the angular velocity of the nail in rad/hour?
Homework Equations
w= v/r
The Attempt at a Solution
First I will convert 55 miles into inches.
55 mile * 5280 FT/mile * 12 Inches/FT = 3484800 inches.
Velocity = 3484800 INCH/HR
R = 6.5 INCH
Thus:3484800 / 6.5 = 6969600 inch/hr
(Is this correct so far)...
then how do I convert that into rad/hr...?
Is there a formula that I am not aware of?
Please help. thank you,.
