- te ca y Averach A force of magnitude 7.10 units acts on an object at the origin in a direction = 34.0 above the positive x-axis. (See the figure below.) A second force, of magnitude 5.00 units acts on the object in the direction of the positive y-axis. Find graphically the magnitude and direction of the resultant force poros SC . Orch A man in a maze makes three consecutive displacements. His first displacement is 8.60 m westward, and the second is 24.0 m northward. At the end of his third displacement he is back to where he started. Use the graphical method to find the magnitude and direction of his third displacement. Ser92 A person walks 23.0' north of east for 2.90 km. How far due north and how far due east would she have to walk to arrive at the same location? Need ? - Seco LMP.963. Vys k Your Teache The magnitude of vector is 17.0 units and points in the direction 330 counterclockwise from the positive x-axis. Calculate the x- and y-components of this vector.

Answer 1

Fi = 7.10 cosos +7.10 sino F2 = 5 Fi+ = 7.10 cosoi +(5+7.10 simoy il. = 7.10 cos34 h +(5+7.10 sin 340) = 5.886478.97096 | Fi +E) - 5588678.9702 2 10.72N O = Taul (8.970 ( 5.886 = 56.75° 788 + F K-256.753 Ã = 25.49 m id ] = 58602+242 = 2 direction ga Tañl (34) = 70.285° tus Noth = 2.9x Sin 230 = 1.133 km East = 2.9xCos23 = 2.669 km

my 330° counter clock wise = 330° -360* = -300 clock coise Magneluche = 17 cines . so the vector is 17(cos(-30) it senc-30);) Age = 17x cos(-30) =14.722 units Ay = 17 x Sint-30) = -8.5 units
