F_2 = 25 N vartheta_2 = 170^circ ccw from +x-axis Find: F_1 + F_2 Find the magnitude of the resultant R of the vector displacements C and D whose components (in km) along three perpendicular directions are: C_x = 5 D_x = -3 C_y = 0 D_y = 4 C_z = -2 D_z = 6 The x-component of a certain vector is -25 units and the y-component is +49 units. What is the magnitude of the vector? What is the angle between the vector and the +x-axis? A person wants to reach a point 3.4 km from her present location and is in a direction 35^circ E of N. However, she must travel along streets that go either N-S or E-W. What is the minimum distance she could travel to reach her destination? Two vectors of length a and b make an angle vartheta with each other when placed tail-to-tail. Show by taking components along two perpendicular axes that the length of their sum is: r = sqrt{a^2 + b^2 + 2ab cos vartheta} use the figure below as a guide
