Question

MEDAL GIVEN TO CORRECT ANSWER.
A water skier is pulled behind a boat by a rope. The rope has a tension of 450 N and is at an angle of 21°. What is the y-component of the tension?

A. 213 N
B. 420 N
C. 450 N
D. 161 N

Answer 1

I am assuming the angle is in the y-direction. If so, the tension of the rope is the hypotenuse and the y-component is opposite from the angle.

Answer 2

Thus, sin(21 deg)=y/450

Answer 3

and y=450*sin(21 deg)

Answer 4

so, it's D?

Answer 5

Yup :)
