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?
What is the speed (in m/s) of the Galapagos Islands, on the earth's equator, due to our planet's spin on its axis? What is the earth's speed (m/s) due to its rotation around the sun?
