- What is the relationship between the mass of each object and the force of gravity? O Mass of each object is directly proportional to the force of gravity. O Mass of each object is ONLY inversely proportional to the force of gravity. O Mass of each object is inversely proportional to the square of the force of gravity O Mass of each object is proportional to the square of the force of gravityProblem 3. Rising Snake A snake of length L and linear mass density p rises from the table from rest. It pushes its head straight up with the constant velocity v. The part of the snake which is on the table is not moving. 1. What is the normal force that the snake exert on the table? 2. What is the tangential (parallel to the surface of the table) force that the snake exert on the table? 3. What is the minimal coefficient of friction between the snake and the table which would allow the snake to raise like that? 4. What is the total mechanical work which the snake will have done when it rises full length?In Figure 1, we depict two boxes and an applied force of magnitude 100.0N. The horizontal floor is frictionless, and box A is more massive thanbox B. Which of the following is correct? (Before you answer this question, draw FBDs and sum forces.)a. Box A pushes on box B with a force of 100 N, and box B pusheson box A with a force of 100 N.b. Box A pushes on box B harder than box B pushes on box A.c. Boxes A and B push on each other with equal forces of less than 100.0N.d. The boxes will not begin to move unless the total weight of the twoboxes is less than 100.0 N.
