A block is pulled at a constant speed along a rough 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 In along the horizontal surface. F 210 I p = 0.33 What is the work done by the resultant force acting on the block? The acceleration due to gravity is 9.8 m/s2 . Suppose that the force on the block FT is increased so that the block accelerates (start- ing from rest) at a = 2.4 m/s2. Now what is the net work done by all the forces acting on the block as it moves a dis- tance of 15 In? Answer in units of J. O 1. Wm = 0 O 2. Wm = 7717.5J O 3. Wm; = 848.925 J O 4. Wm; = 1851.44J O 5. Wm = 2546.78 J O 6. Wm = 12862.5 J O 7. Wm = 1017.42 J Your response... PALETTE
