Oh right you make it so simple! Thanks.
So change in velocity over change in time. Change in time is 0.02sec
change before
119.1 -114.2 = 4.9deg
4.9/0.02=245deg
change after
123.4 - 119.1 = 4.3deg
4.3/0.02=215deg
(245+215)/2= 230deg.sec-1
Accel= change of rate of velocity is (230-245)/2...
Homework Statement
The following data are for the angular displacement of the knee in cycling
measured in degrees. Using radian measure, compute the angular velocity
and acceleration when the knee angle is 119.1 degrees. The sampling
frequency was 50 Hz. What is a problem you may...
Thank you very much. :)
tanθ = y/x was helpful! My answer came close within a degree, but I suppose there was issues rounding, I'll ask my teacher what he wants.
Homework Statement
Calculate the knee joint angle based on the XY coordinates of the hip, knee
and ankle joint centres.
Hip joint(x = 1.0183, y = 0.7959)
Knee joint(x = 1.1223, y = 0.5042)
Ankle joint(x = 1.0539, y = 0.1081)
