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?

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)

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).
