Mikaela is out for a bike ride on a breezy day. The wind blows out of the west such that it exerts a constant drag force Farag of 105 N pointing east. Initially riding north on S. flat roads, Mikaela traverses a 1.60 km long circular arc at a constant specd that ends with her heading directly into the wind; the are is a quarter circle that starts pointing north and ends pointing west, as shown in the figure. A. How much work W does the wind do on her as she rounds this curve from point A to point B? W = + TOOLS x10
