Robert Hornbuckle ums Calendar Gradebook 18> Assessment cular Motions and Gravitation Due in 8 hours, 22 minutes. Due Sat 09/15/2018 11:59 pm Semi-trailer trucks have an odometer on one hub of a trailer wheel. The hub is weighted so that it does not rotate, but it contains gears to count the number of wheel revolutions-it then calculates the distance traveled. If the wheel has a 1.1 m diameter and goes through 100000 rotations, how many kilometers should the odometer read? Preview unit: km License Points possible: 1 Unlimited attempts. Submit

Explanation / Answer

d=1.1 m

r= 1.1/2= 0.55 m

delTheta= 100000*(2*3.14/1)

=628000 rad

delTheta= delS/r

delS=r*delTheta

= 628000*0.55

= 345400 m

= 345.4 km
