Question:I need aid with this Physics problem. Basically I am given that a car's wheel diameter of 67cm and that the wheels spin at 108 rad/s. What I involve to find out is how fast the coup¨¦ is moving in km/h. How do I solve a problem resembling this?
Answers:
such big wheels? incredible!
diameter 0.67 meters * PI = 2,104867078 meters circumference
1 rad/s = 3600 rad/h = 7577,52148 meters/h = 7.57752148 km/h
108 rad/s is also incredible,
108 rad/s = 388800 rad/h = 818,3723199 km/h
