Answer #1

normal force acting on marked book

F = (number of books including marked * mass of each book ) g

F = ( 7 * mbook) g

option (c) is correct.

    I A box, mass 4.0 kg, has an initial velocity of V +3.0m/si (see the coordinate system in the figure). So it's moving to the right initially. A force FA-15.0 N is being applied, at an angle 18. The mass slides on a table with friction. The coefficient of kinetic friction between the table and box is 0.30 FA (a) Make a force diagram. (b) Obtain the Normal force. (As you can see, the normal force is NOT equal to...
