This assignment is due at 9:00PM Monady, September 14, 2009 001 10.0 points Four vectors, each of magnitude 13 m, lie along the sides of a parallelogram as shown in the figure. The angle between vector A and B is 50 ◦ . Hint: Remember you are adding four vec- tors. A 1 3 m C 13 m B 13 m D 1 3 m 50 ◦ What is the magnitude of the vector sum of the four vectors? Answer in units of m. 002 10.0 points Bob heads out into a lake at an angle of 36 ◦ with respect to the shore. If his boat is capable of a speed of 2 . 8 m / s, how far from land will he be in 7 min and 21 s ? Answer in units of m. 003 (part 1 of 2) 10.0 points A roller coaster travels 201 ft at an angle of 33 . 6 ◦ above the horizontal. How far does it move horizontally? Answer in units of ft. 004 (part 2 of 2) 10.0 points How far does it move vertically? Answer in units of ft. 005 (part 1 of 2) 10.0 points A particle undergoes three consecutive dis- placements: vector d 1 = d 1 x vector i + d 1 y vector j + d 1 z vector k vector d 2 = d 2 x vector i + d 2 y vector j + d 2 z vector k vector d 3 = d 3 x vector i + d 3 y vector j , where d 1 x = 2 . 54 cm , d 1 y = 3 . 42 cm , d 1 z =- 1 . 15 cm , d 2 x = 2 . 14 cm , d 2 y =- . 919 cm , d 2 z =- 4 . 06 cm , d 3 x =- 2 cm , d 3 y = 3 . 13 cm ....
