Suppose an object is accelerated by a force of 100 N. Suddenly a second force of 100 N in the opposite direction is exerted on the object, so that the forces cancel. The object:1) is brought to rest rapidly.2) continues at the velocity it had before the second force was applied.3) is brought to rest and then accelerates in the direction of the second force.4) decelerates gradually to rest.5) is brought to rest and then accelerates in the direction of the second force. 6) is brought to rest rapidly. 7) continues at the velocity it had before the second force was applied.
