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 b
etween the tires and the road to become zero. While the car is on the ice, it ____. a. moves along a straight-line path away from the center of the circle. b. moves along a straight-line path toward the center of the circle.
c. moves along a straight-line path in its original direction.
d. continues to follow a circular path, but with a radius larger than the original radius.
e. moves along a path that is neither straight nor circular.
The car travels with centripetal acceleration which is directed to the center of the circle but the velocity is changing since the car faces different direction as it travels in the circular direction. When the friction is zero between the tires of the car and the road, it will continue in the direction of its tangential velocity which will be along a straight-line path in its original direction.
<span>The following that describes the intercepts on the graph is "The initial velocity of the runner was 4 m/s, and the runner stopped after 8 seconds." It is because the starting point of the line is at 4 and then the ending point is at 8.
