A 35 kg block is pulled at a constant speed along a horizontal surface by a rope with tension FT . The rope is inclined at an angle from the horizontal as shown. The block moves a

distance 15 m along the horizontal surface.
What is the net work done by all the forces acting on the block? The acceleration of gravity is 9.8 m/s

1. Wnet = 5145 J
2. Wnet = −2726.85 J
3. Wnet = −5145 J
4. Wnet = 2726.85 J
5. Wnet = 1968.75 J
6. Wnet = −1430.38 J
7. Wnet = 0
