5. What is the component AxAx of vector A 3A3 in the coordinate system (3)? (Express your answer to two significant figures.)

6. What is the component AyAy of vector A 3A3 in the coordinate system (3)? (Express your answer to two significant figures.)

What are the components Ax and Ay of vector A in the three coordinate systems shown in the figure below? A1 = 4.6, A2 = 5.5, A3 = 4.5. 120° Ai 30° A2 30°

Explanation / Answer

In 1]

Ax component of A1 is:

x-component = 4.6cos30 = 3.984

and Ay component of A1 is:

y-component = 4.6sin30 = 2.3

in 2]

x-component = 5.5cos120 = - 2.75

and Ay component of A1 is:

y-component = 5.5sin120 = 4.763

3]

x-component = - 4.5cos30 = - 3.897

and Ay component of A1 is:

y-component = - 4.5sin30 = - 2.25.
