Two students, Student X and Student Y, stand on a long skateboard that is at rest on a flat, horizontal surface, as shown. In order to get the student-student-skateboard system to accelerate, Student X claims that Student Y should apply a force on Student X while both students stand on the skateboard. Which of the following statements is true regarding the claim made by Student X? a)The claim is correct because Newton’s second law states that an object will accelerate if a net force is applied to the object. b)The claim is correct because Student Y can apply a force that is greater in magnitude than the frictional forces that are exerted on the student-student-skateboard system. c)The claim is incorrect because Student Y cannot apply a force that is greater in magnitude than the frictional forces that are exerted on the student-student-skateboard system. d)The claim is incorrect because both students are internal to the student-student-skateboard system, and internal forces within a system cannot cause the system to accelerate.
