Question

What are the components of a vector with a magnitude of 4.00 and a direction of -112 degrees?

A. (1.50, 3.71)

B. (-1.50, -3.71)

C. (-3.71, -1.50)

 D. (-1.12, -1.78)

Answer 1

What are the components of a vector with a magnitude of 4.00 and a direction of -112 degrees?

A. (1.50, 3.71)

B. (-1.50, -3.71)

C. (-3.71, -1.50)

 D. (-1.12, -1.78)

x-comp = 4 x cos(-112) = -1.5

y-comp = 4 x sin (-112) = -3.71

B is the correct answer
