A student is on a skateboard facing a wall. The student and skateboard have a mass of 75 kilograms. The student pushes off of the wall with a force of 100 Newtons. What is the force of the wall pushing back on the student? What is the acceleration of the student as she moves away from the wall?

Answer:

F=-100N; a=1.3m/s^2

Force is being made by student, so wall counteracts that force by not moving so it is equally opposite.
