Answer:
The magnitude of the vertical component of vector u is
The magnitude of the horizontal component of vector u is
Step-by-step explanation:
A vector quantity has, a magnitude and a direction
The horizontal component of vector is ║u║ cos α
The vertical component of vector is ║u║ sin α
∵ The magnitude of vector u is 12 ft
∵ The measure of angle α is 135°
- Substitute the magnitude and the angle in the rule of
each component
∴ = 12 cos(135)
∴ = 12 sin(135)
∵ cos(135) =
∴ = 12 ( )
∴ =
- The magnitude of a number means the number without its sign
∴ The magnitude of the horizontal component of vector u is
∵ sin(135) =
∴ = 12 ( )
∴ =
∴ The magnitude of the vertical component of vector u is
