an elk runs a pattern given by the four displačement 3.20 m, and B = 5.10 m and C = 4.80 m. Determine the magnitude and direction of the last displacement is displacement and ends its displacement at the same location, i.e, R, = Ry = 0. {Consider determining %3D

1. ANALYTICAL METHOD OF ADDING VECTORS Solve the same problem as PART 1 but this time analytically. START with the values below. DO NOT USE VALUES FROM PART 1. Suppose you first walk A = 12 m in a direction 20° west of north and then B= 20 m in a direction 40° south of west. Let the +x-axis coincide with the easterly direction and the +y-axis with the northerly direction. Note: In this problem, do not round values if you need to use them for calculations in subsequent parts. Rounding errors can propagate and can make your final answer lie outside the tolerance limit of 5% set for this problem. Keep all answers to 4 significant figures.

37. Go The components of vector A are A, and A, (both positive), and the angle that it makes with respect to the positive x axis is 0. Find the angle 0 if the components of the displacement vector A are (a) A, = 12 m and A, = 12 m, (b) A, = 17 m and A, = 12 m, and (c) A, = 12 m and A, = 17 m. %3D

QI: a A displacement veetor in the ry plane is 15 m long and directed at angle u 30° in below Figure Determine (a) the x component and (b) the y component of the vector.

#7) It is a nice day outside and you decide to go for a bike ride to your friend's house. After leaving your house, you get on your bike and peddle 3.50 km north, 8.00 km east (or eastward - meaning from west to east), and then 4.50 km South. Determine the magnitude of the resultant displacement mathematically. Drawing a diagram might help. Report answer to 3 sig figs, show all your work, show your starting equations first before plugging in numbers.

The X component of a displacement vector or is -153 m, well it why component is -180 m find the magnitude of r

35. Which of the following statemenis is/are true about the laser? (1) (2) (3) There is population inversion for its production. LASERS are used to performi keyhole operations. It is an acronyın for long amplification by stimulated emission of radiation.

Let: vector L = 3.0 m, 45º Southeast vector M = 4.0 m, 60º Northwest. vector N = 2(vector L) – vector M Find: a) x-component of vector N b) direction of C

An old lady, to maintain her health during morning walk, covers three displacements. The first has a magunitude of 200 m and makes an angle of 110 with the positive x axis. She covers second displacement wich has magnitude of 300 m at an angle of 20 west of south and then she covees third displacement. The resultant displacement has magunitude of 420 m and is direct at an angle of 45.0 to the positive x axis. Find the magunitude and direction of third displacement
