Question

The magnitude of vector A is 6.3 m. It points in a direction which makes an angle of 1459 measured counterclockwise from the positive x-axis. (a) What is the x component of the vector -3.5A? (b) What is the y component of the vector-3.5A? (c) What is the magnitude of the vector -3.5A?

Answer 1

Answer:

Explanation:

Length of vector, A = 6.3 m

Angle from x axis, θ = 1459°

(a) The X component of - 3.5 A

= - 3.5 x 6.3 x Cos 1459 = - 20.85 m

(b) The Y component of - 3.5 A

= - 3.5 x 6.3 x Sin 1459 = 7.178 m

(c) The magnitude of vector - 3.5 A = - 3.5 x 6.3 = 22.05 m

(c)
