The mass of a robot is 34 kg. It is traveling at 2 m/s when it collides with the fence. According to Newton's third law, which describes the result? A. The robot exerts a force of 68 N on the fence; the fence absorbs the force. B. The robot exerts a force of 34 N on the fence; the fence moves 2 meters. C. The robot exerts a force of 68 N on the fence; the fence exerts a force of 68 N on the robot. D. The robot exerts a force of 68 N on the fence; the fence exerts a force of 34 N on the robot.

Answer :

Here, Force = m * a = 34 * 2 = 68 N

According to Newton's third law, fence will exert equal and opposite force (by direction) on the robot.

In short, Your Answer would be Option C) The robot exerts a force of 68 N on the fence; the fence exerts a force of 68 N on the robot. 

Hope this helps!
