- I'm having trouble finding the solution to this problem. This problem is based off the textbook "Physics: Principles with Applications, 7th edition by Douglas C. Giancoli" chapter 16.arrow_forward__q22.34__ it is your job to determine all the possible unit vectors whose angle with the + section of the x axis is pi/3 and with the + section of the y axis is pi/4.arrow_forwardwhat is the b ? a)95.65 b)98.70 c)100arrow_forward

(b) How far (in meters) can theimpulses travel in 5.0 ms?arrow_forward21) Let ⃗A=6^i−8^j, ⃗B=−8^i+3^j, and ⃗C=26^i+19^j. If a⃗A+b⃗B+⃗C=0, calculate the variables a and b.arrow_forwardPerform the following arithmetic operations, keeping the correct number of significant figures in your answer. a. The product 56.2 0.154 b. The sum 9.8 + 43.4 + 124 c. The quotient 81.340/arrow_forward
- The two-dimensional vectors A and B both have magnitudes of 7.00 m. If A+B=4.00m, what is the angle between A and B?arrow_forwardA pirate has buried his treasure on an island with five trees located at the points (30.0 m, 20.0 m), (60.0 m, 80.0 m), (10.0 m, 10.0 m), (40.0 m, 30.0 m), and (70.0 m, 60.0 m), all measured relative to some origin, as shown in Figure P1.69. His ships log instructs you to start at tree A and move toward tree B, but to cover only one-half the distance between A and B. Then move toward tree C, covering one-third the distance between your current location and C. Next move toward tree D, covering one-fourth the distance between where you are and D. Finally move toward tree E, covering one-fifth the distance between you and E, stop, and dig. (a) Assume you have correctly determined the order in which the pirate labeled the trees as A, B, C, D, and E as shown in the figure. What are the coordinates of the point where his treasure is buried? (b) What If? What if you do not really know the way the pirate labeled the trees? What would happen to the answer if you rearranged the order of the trees, for instance, to B (30 m, 20 m), A (60 m, 80 m), E (10 m, 10 m), C (40 m, 30 m), and D (70 m, 60 m)? State reasoning to show that the answer does not depend on the order in which the trees are labeled. Figure 1.69arrow_forward
