Question

Here's a stationary bike. If you pedal such that the front wheel rotates at 6.9 rad/s, and that wheel's radius is half a meter, how far would you have gone in 35 minutes, if the bike where a non-stationary bike? (Assume a constant speed of rotation)

I am not sure where to start other than maybe using the formula s=or and converting the minutes to seconds. Would you have to use a linear equation?

Answer 1

r dθdt = .5 * 6.9 = 3.45 m/s is the linear speed.

so, 3.45 m/s * 35*60 s = 7245 m
