Question Video Finding The Horizontal Component Of A Vector Nagwa A unit circle has a radius of one. cosine is the x coordinate of where you intersected the unit circle, and sine is the y coordinate. or if you had a vector of magnitude one, it would be cosine of that angle, would be the x component, for the, if we had a unit vector there in that direction. and then sine would be the y component. Measure of the angle is given to us indirectly. always remember that the vector (looks like a ray) and the positive x axis forms the angle. since we are given 75 degrees as our angle, we subtract it from 180 degrees to get 105 degrees. this 75 degrees angle is formed with the vector and negative x axis.

A Vector Is In Horizontal Direction And Makes An Angle 30 Degree The hypotenuse of the vector = 32. the angle of the vector = 45°. therefore, the vector component in the y axis is given as follows; vy = vsinθ v y = v sin θ. substituting the values from the question we get. vy = 32×sin(45∘) ≈22.6 v y = 32 × sin ( 45 ∘) ≈ 22.6. the vector component in the y axis, is approximately 22.6. You are right that arctan(7 10) yields two answers in the range 0 360 degrees, but the vector u is in the second quadrant (u= 10i 7j), and so its angle cannot be 325 degrees, even though a vector with that angle has the same slope tangent value. a vector with a direction of 325 degrees would be in the fourth quadrant. Label its magnitude and the angle that it makes with the horizontal. draw a rectangle about the vector such that the vector is the diagonal of the rectangle. beginning at the tail of the vector, sketch vertical and horizontal lines. then sketch horizontal and vertical lines at the head of the vector. the sketched lines will meet to form a. Examples of components of a vector. example 1: find the x and y components of a vector having a magnitude of 12 and making an angle of 45 degrees with the positive x axis. solution: the given vector is v= 12, and it makes an angle θ = 45º. the x component of the vector = v x v x = vcosθ = 12.cos45º = 12. (1 √2) = 6√2.

A 400 n force is exerted at a 60 degree angle (a direction of 300 degrees) to move a railroad car eastward along a railroad track. a top view of the situation is depicted in the diagram. the force applied to the car has both a vertical (southward) and a horizontal component (eastward). Vector a a makes an angle of θ a θ a with the x axis, and vector b b makes and angle of θ b θ b with its own x axis (which is slightly above the x axis used by vector a). figure 5.23 to add vectors a a and b , b , first determine the horizontal and vertical components of each vector.
