The Initial Point for the Vector Is the Origin, And \theta

question 7

Multiple Choice

The initial point for the vector is the origin, and $\theta$ denotes the angle (measured counterclockwise) from the $X$ -axis to the vector. The magnitude of $\mathrm { V }$ is $30$ cm/sec, and $\theta = 120 ^ { \circ }$ Compute the horizontal and vertical components of the given vector. (Round your answers to two decimal places.)

• A) \(V _ { x } = 25.98\) cm/sec \(V _ { y } \approx - 15\) cm/sec
• B) \(V _ { x } = 15\) cm/sec \(V _ { y } \approx 25.98\) cm/sec
• C) \(V _ { z } = - 15\) cm/sec \(V _ { y } \approx 25.98\) cm/sec
• D) \(V _ { x } = 21.21\) cm/sec \(V _ { y } \approx 21.21\) cm/sec
• E) \(V _ { x } \approx - 25.98 \mathrm {~cm} / \mathrm { sec } V _ { y } \approx 15 \mathrm {~cm} / \mathrm { sec }\)
