Which statement about the motion of this object is correct?

• The object turned around and sped back to its original location at the 9-second mark

• The object started from rest and had a speed of 10 m/s over a 5-second period

Which conclusion can be reached from the diagram?

• The forces on the object are unbalance because there are different amounts of force in different directions

• The forces on the object are unbalanced because different forces are applied to the object in different directions

• The forces on the object are balanced because the up and down forces are less than the right and left forces

• The forces on the object are balanced because the up and down forces are equal, and the right and left forces are equal

What can be predicted about the motion of the toy car?

• The toy car experiences a net force of 0 N and is at rest

• The toy car experiences a net force of 5 N and is at rest

• The toy car experiences a net force of 0 N and moves in the forward direction

• The toy car experiences a net force of 5 N and moves in the forward direction
