Question

Using the diagram below, write a. in terms of Au b. in terms of AB and B A 2. Add the following vectors using the Triangle Law. a. 9 N on a heading of (S2"W) and 11 N on a heading of (N31*W). b. 7 m/s on a bearing of 30 and 2 m/s from a bearing of 343". (HINT: a vector "on" a bearing extends "out" from the origin and a vector "from" a bearing is directed in "toward" the origin) 3. Add the following vectors using the Component law a. 9 m/s (N30°E) and 2 m/s [N 80'E). b. 3 N in a direction 15" south of west and 4 N in a direction 12 east of south. 4. A plane is heading on a bearing of 200 with an airspeed of 400 km/h when it is blown off course by a wind of 100 km/h from the northeast Determine the resultant ground velocity of the plane. в M 0 18 Feb 血

Answer 1

a. Au = 9cos(30) + 11cos(31)

b. AB = 9sin(30) + 11sin(31) and B = -9sin(30) + 11sin(31)

3. a. 9cos(30) + 2cos(80)

b. 3cos(15) + 4cos(12)

4. The ground velocity of the plane would be 349.4 km/h on a bearing of 225°.
