Observation 1: Try to stop a ball coming towards you,so as to save a boundary, by applying a force of some magnitude in the opposite direction of the motion of the ball.Observation 2: In the same case, you apply the force of same magnitude but in same direction of the motion of the ball.Observation 3: In the same case, you apply the force in the opposite direction of the motion of the ball but its magnitude is less.In which case/cases will you be able to stop the boundary. Why is that?

Answer» Observation 1: Try to stop a ball coming towards you,so as to save a boundary, by applying a force of some magnitude in the opposite direction of the motion of the ball.



Observation 2: In the same case, you apply the force of same magnitude but in same direction of the motion of the ball.



Observation 3: In the same case, you apply the force in the opposite direction of the motion of the ball but its magnitude is less.



In which case/cases will you be able to stop the boundary. Why is that?
