Consider the circle with center X, as shown in the figure.
Draw the diameter of the circle which is parallel to cherd AB, as shown in the figure.
Since the diameter and AB are parallel, then the line segment XC which bisects AB at C, will be perpendicular to AB.
SO triangle XCB is a right triangle. Thus the length of CX, by the Pythagorean theorem is
units.
Answer: 8 units

Given:
Two vectors are:
To find:
The projection of u onto v.
Solution:
Magnitude of a vector is:
Dot product of two vector and
is:
Formula for projection of u onto v is:
On further simplification, we get
Therefore, the projection of u onto v is .
