Suppose an object is accelerated by a force of 100 NN. Suddenly a second force of 100 NN in the opposite direction is exerted on the object, so that the forces cancel. The object Suppose an object is accelerated by a force of 100 . Suddenly a second force of 100 in the opposite direction is exerted on the object, so that the forces cancel. The object continues at the velocity it had before the second force was applied. is brought to rest and then accelerates in the direction of the second force. is brought to rest rapidly. decelerates gradually to rest.
