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(a) is brought to rest rapidly.(b) decelerates gradually to rest.(c) continues at the velocity it had before the second forcewas applied.(d) is brought to rest and then accelerates in the direction of the second force.
