A strength and conditioning coach recommends that an athlete train by pulling a large amount of mass while sprinting. If action-reaction forces are always equal and opposite, which explanation best describes the action reaction pair acting on the runner ? A) The runner will not move because the applied force exerted by the runner on the mass will create an equal and opposite frictional force, canceling the applied force
B) The runner will accelerate forward because the applied force exerted by the runner creates an equal and opposite frictional force by the ground, but these forces are exerted on different objects.
С) The runner will accelerate forward because the force of friction by the mass on the runner is always less than the applied force by the runner, resulting in a net force forward
D) The runner will remain motionless because the applied force by the runner in the forward direction is less than the frictional force from the ground, acting in the opposite direction.
