Question:
(a) Draw a free-body diagram for the man and for the mattress.
(b) Identify the reaction forces for all the forces in your free-body diagrams in part (a).
(c) If the mass of the man is 110 kg and the mass of the mattress is 2.5 kg, what is the upward force of the water on the mattress? What is the force that the man exerts on the mattress?

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
