The relative angle at the knee changes from 0degree to 85deg

The relative angle at the knee changes from 0degree to 85degree during the knee flexion phase of a squat exercise. If 10 complete squats are performed, what is the total angular distance and the total angular displacement undergone at the knee? (Provide answers in both degrees and radians.)

Solution

10 x (85/180) = 14.8 radians

10(85)=850degrees
