In physics, work is equal to the product of force and distance, given that the direction of force is the same with the direction of the distance.
W = Fd
The total force is F = 1,700 N + 500 N = 2,200 N Now, if the question is the work needed to lift the barbell from the ground, the distance would be 2 m. Hence, the work would be
Let the total amount of pages be t t=30+1/8t+2/8t now simplify t=30+3/8t 5/8t=30 divide 30 by 5 1/8=6 now you know 1/8 of the book is 6 pages which means the whole book has 48 pages.
