A snowboarder is pulled by a rope that exerts a force of 250 N at an angle of 30° above the horizontal. What are the horizontal and vertical components of the force?
SOH CAH TOA
Fx = 216.5 N
Fy = 125.0 N
Fx = 125.0 N
Fy = 216.5 N
Fx = 250.0 N
Fy = 125.0 N
Fx = 125.0 N
Fy = 62.5 N
A construction crane pulls a load upward with a cable applying 500 N of force at an angle of 45° to the horizontal. What are the components of the force?
SOH CAH TOA
Fx = 500 N
Fy = 0 N
Fx = 353.6 N
Fy = 353.6 N
Fx = 250 N
Fy = 433 N
Fx = 433 N
Fy = 250 N
A child pulls a sled with a rope that applies a force of 120 N at an angle of 40° above the horizontal. What is the y component of the force (Newtons)?
SOH CAH TOA
(a)

(a)
81 N
88 N
102 N
110 N
A rescue worker is using a rope to pull a stranded hiker up a slope. The rope applies a force of 60 N vertically upward and 80 N horizontally forward.
