Can light bend around corners?

In which of the following scenarios are you in equilibrium?

a. standing still on a chair

b. sliding straight down an icy hill at a steady speed

c. sliding around a corner at the bottom of that icy hill

When you take your 1200- car out for a spin, you go around a cornerof radius 59 with a speed of 18 . The coefficient of staticfriction between the car and the road is 0.88.
Assuming your car doesn't skid, what is the force exerted on it bystatic friction?
