MULTIPLE CHOICE QUESTION

Media Image

Two ropes are attached to a wagon, and each is pulled with 10 N of force, as shown. What will be the wagon's motion when the ropes are pulled at the same time?

As long as the forces on the ropes remain constant, the wagon will move in a circle.

As long as the forces on the ropes remain constant, the wagon will slowly raise off the ground.

The forces will cancel out because they are equal and opposite, and the wagon will not move.

The wagon will rock steadily back and forth, about a meter in each direction, due to the applied forces.

A car is moving in a straight line at constant velocity. What statement best predicts the car’s continued motion?

The car will come to a complete stop when the slowing forces are less than the forces propelling it forward.

The car will begin to move right or left at a new velocity because there are no new changes in the forces that continue to act on the car.

The car will begin to speed up when the slowing forces are greater than the forces propelling it forward.

The car will continue to move in a straight line at the same velocity as long as the same forces continue to act on the car.
