Suppose a particle is being accelerated through space by a 10-N force.Suddenly the particle encounters a second force of 10 N in the opposite direction from the first force.The particle with both forces acting on it
A)is brought to a rapid halt.
B)decelerates gradually to a halt.
C)continues at the speed it had when it encountered the second force.
D)theoretically tends to accelerate toward the speed of light.
E)none of these

Quizplus · Accepted Answer

When the two forces are equal and opposite, they cancel each other out, resulting in no net force on the particle. According to Newton's first law of motion, the particle will continue moving at a constant velocity, which is the speed it had when it encountered the second force.
