1.

You are making a circular turn in your car on a horizontal road when you hit a big patch of ice, causing the force of friction between the tires and the road to become zero. While the car is on the ice, it

moves along a straight-line path in its original direction.

moves along a straight-line path away from the center of the circle.

moves along a straight-line path toward the center of the circle.

moves along a path that is neither straight nor circular.

continues to follow a circular path, but with a radius larger than the original radius.

2.

When a car goes around a circular curve on a horizontal road at constant speed, what force causes it to follow the circular path?

the friction force from the road

gravity

No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration.

the normal force from the road

3.

When an object moves in uniform circular motion, the direction of its acceleration is

in the same direction as its velocity vector.

depends on the speed of the object.

is directed toward the center of its circular path.

is directed away from the center of its circular path.

in the opposite direction of its velocity vector.

4.

When a bobsled goes around a banked circular curve and slided up on the side of the track, what force cause it to follow the circular path?

the normal force from the track

the friction force from the track

gravity

No force causes the car to do this because the car is traveling at constant speed and therefore has no acceleration

A skateboarder is trying to take a sharp turn (radius of 1.2m) on a road with a coefficient of friction of 0.53. She grabs hold of a tree branch to help make the turn. If she makes the turn going 3.2 m/s, what force does she need to pull with to make the turn? The mass of the girl and board together is 35 kg.
Draw the Free Body Diagram for the situation.

A particularly scary roller coaster contains a loop-the-loop in which the car and rider are completely upside down. If the radius of the loop is 13.2m with what minimum speed must the car traverse the loop so that the rider does not fall out while upside down at the top? Assume the rider is not strapped to the car.
