2)
The momentum of your car
Points radially inward, toward the center of the track.
Points radially outward, away from the center of the track.
Points forward, in the same direction you are moving.
Points backward, opposite to the direction you are moving.
Is zero.
Explanation / Answer
1)
The acceleration comes from the force, and since the acceleration is pointing inward during circular motion, the force must be pointing inward. Objects moving in a circle always have a component of acceleration, called centripetal, which is toward the center of the circle. Option a
2)
Since momentum is directly related to velocity, it makes sense that it would lead in the same direction as the velocity, which, in circular motion, points in the same direction as the tangent to the circle. This means option c is correct Points forward, in the same direction you are moving
