Question

What are the x and the y components of a 25 m
displacement at an angle of 210° with the x-axis
(clockwise) ?
(A) – 25 cos 30º and + 25 sin 30°
(B) 25 cos 30º and – 25 sin 30°
(C) 25 cos 30º and + 25 sin 30°
(D) - 25 cos 30º and – 25 sin 30°​

Answer 1

Answer:the answer would be the 2nd option

Explanation:

I have attached a solution it is based on the unit vectors for x and y axes

Answer 2

sin(30°) =y/25

1/2=y/25

therefore, y=12.5

cosine (30°) =x/25

√3/2=x/25

there fore x=21.66 approximately
