m Ac = m v^2/r
= 1700 * 400 / 55 Newtons
When you take your 1700-kg car out for a spin, you go around a corner of radius 55 m with a speed of 20 m/s. The coefficient of static friction between the car and the road is 0.88.Assuming your car doesn't skid, what is the force exerted on it by static friction?
