Transcribed Image Text:3. A force of 7 N, applied at an angle of 30° to the horizontal, is
required to drag a book across the table at a constant velocity of
0.7 m/s. If the mass of the book is m=2kg, determine: (a) the
coefficient of kinetic friction between the book and the table, (b)
the work done on the book by the applied force If the block is
pulled for a total of 3 seconds.
Draw the free body diagram
