Question
The following three vectors represent the position of the hip, knee, ankle of a cyclist in a 2- dimensional, stationary frame. Use the following diagram and values for vectors v1, v2, and v3 to answer the following questions. ???
v1 is top vector
v2 is middle vector
v3 is bottom vector
Thigh is top bold line
Shank is bottom bold line
The knee joint is the joint inbetween the two bold lines
v1 = (10.14, 2.52)m
v2 = (10.49, 2.14)m
v3 = (10.30, 1.82)m
Compute the angle of the knee at this instant in degrees.
Explanation / Answer
t t t t t t angle = angle (v1-v2 )- angle (v2-v3)= 73.34
