Unformatted text preview: obaidi (aao476) – OH-07 – Bradley – (191) 1 This print-out should have 21 questions. Multiple-choice questions may continue on the next column or page – find all choices before answering. This is Online Homework No. 7. It is due before 06:00 AM on Tuesday 30 September, UAE Time (which is 09:00 PM on Monday 29 September in Texas), unless otherwise noti- fied. 001 (part 1 of 3) 4.0 points A single conservative force F ( x ) = b x + a acts on a 4 . 83 kg particle, where x is in meters, b = 4 . 99 N / m and a = 6 . 08 N. As the particle moves along the x axis from x 1 = 0 . 918 m to x 2 = 3 . 98 m, calculate the work done by this force. Answer in units of J. 002 (part 2 of 3) 3.0 points Calculate the change in the potential energy of the particle. Answer in units of J. 003 (part 3 of 3) 3.0 points Calculate the particle’s initial kinetic energy at x 1 if its final speed at x 2 is 11 . 6 m / s. Answer in units of J. 004 (part 1 of 2) 5.0 points A 0 . 6 kg bead slides on a curved wire, starting from rest at point A as shown in the figure. The segment from A to B is frictionless, and the segment from B to C is rough. The point A is at height 8 . 5 m and the point C is at height 2 m with respect to point B. The acceleration of gravity is 9 . 8 m / s 2 . A 8.5 m B 2 m C Find the speed of the bead at B. Answer in units of m / s....
