x on question 6 is at the bottom

A 950 kg car is making a left turn as in the diagram to the right. If the car is turning at 6.0 m/s, what is the frictional force (so Fo needed to 60 m turn the car? How long does it take the car to complete the turn if the turn spans 907 (or one fourth a complete circle) 6. A roller coaster cart and the people riding in the cart have a combined mass of 600 kg. When the roller coaster reaches Y, the normal force from the track is pushing up on the coaster with 2000 N of force. The radius of the hill at Y is 20 m. Determine the velocity of the roller coaster at Y. (Ignore friction). Hint: Draw a force diagram and determine what the unbalanced force would be at Y - when the roller coaster has circular motion. &G W
