Travel Trailer Tires And Wheels
I need help with this math question (for the course MCR 3U-A) !?!?
An automobile, travelling at 80 km/h, is towing a trailer. The wheels of the trailer are 40 cm in diameter. A) Determine the angular velocity in rad/s and degrees/s. B) Through what angle does the tire turn in 60s? State your answer in radians and degrees. C) What unit of measurement, radians or degrees, is more appropriate for answers such as those in parts A) and B)? Explain.
If you can just help me get started off, I can do the rest on my own. I'm doing this course independetly (its an ILC course) and I don't have a teacher or anyone to ask for help. Any help is appreciated, and I will chose a best answer for whoever helps me the most.
If the wheel's diameter is 40cm (0.4 m) then it covers 0.4π meters in one revolution (the circumference of the wheel). To see how many revolutions that is per hour, divide 80,000 (80 km in m) by 0.4π. Then divide that by 3600 to get revolutions per second (3600 sec = 1 hr) and multiply this by 360 to get the angular velocity in degrees per second, or by 2π to get radians per second since 1 rev = 360° or 2π radians. Then use those answers for the rest
