Current Attempt in Progress In the figure, a horizontal force Fa of magnitude 18.0 N is applied to a 3.03 kg book as the book slides a distance d = 0.51 m up a frictionless ramp at angle = 30°. (a) During the displacement, what is the net work done on the book by Fa, the gravitational force a the book, and the normal force on the book? (b) If the book has zero kinetic energy at the start of the displacement, what is its speed a the end of the displacement? Use g=9.81 m/s². (a) Number (b) Number Units Units F.

A mountain climber is about to haul up a 90-m length of hanging rope. How much work will it take if the rope weighs 0.65 N/m? Set up the integral that gives the work done. (Type an exact answer, using radicals as needed.)

You drop a 2.50 kg book to a friend who stands on the ground at distance D-13.0 m below. If your friend's outstretched hands are at distance d-1.60 m above the ground (see the figure), (a) how much work W, does the gravitational force do on the book as it drops to her hands? (b) What is the change AU in the gravitational potential energy of the book-Earth system during the drop? If the gravitational potential energy U of that system is taken to be zero at ground level, what is U (c) when the book is released and (d) when it reaches her hands? Now take U to be 100 J at ground level and again find (e) W. (f) AU, (g) U at the release point, and (h) U at her hands. 10000 El

A 60 Nt force is exerted on a 5 kg box at an angle of 60° above the horizontal.  (a)  What is the work done by the 60 Nt force on the box if the box moves a distance of 2 m across the floor? (b)  What is the work done by the normal force?:  (c)  If the box moves at a constant speed, what is the work done by friction on the box?:  (d)  What is the work done by gravity on the box?  (e)  What is the total work done by all of the forces on the box?
