You are riding on a Ferris wheel that is rotating with constant speed. The car in which you are riding always maintains its correct upward orientation;it does not invert. (i) What is the direction of the normal force on you from the seat when you are at the top of the wheel? (a) upward (b) downward(c) impossible to determine (ii) From the same choices, what is the direction of the net force on you when you are at the top of the wheel?

Calculate the magnitude of the normal force on a 25.2 kg block resting on a surface that is tilted up at a 40.8° angle with respect to the horizontal.

Shown are the forces acting on the box. Which of the folllowing is true: Choices: P = f and N = Fg P = f and N >Fg none of these P >f and N f and N = Fg

Consider the following statement: “The normal force on an object is always equal to the weight of the object.”Select all the reasons that this statement is false .       The normal force is not always parallel to the force of gravity     The normal force is independent of the force of gravity     The normal force is only equal to the weight of the object when sitting on a horizontal surface and there are no other forces in the y-direction except gravity     The normal force causes an acceleration and therefore does not interact with gravity
