Unformatted text preview: obaidi (aao476) OH07 Bradley (191) 1 This printout should have 21 questions. Multiplechoice 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 particles 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....
