3. After watching a video of Steph making 105 consecutive 3-pointers, an analyst wants to study his kinematics during shooting. At the specific instant in time, the following variables were measured: Linear velocity of shoulder: Vš = + 0.1 ™ ƒ S rad Angular velocity of wrist w.r.t. elbow: ww/ = -8 k S rad Angular velocity of elbow w.r.t. shoulder: w WE/S = +2 k S The upper arm is at 0 = 39° w.r.t. the horizontal axis. The angle between the upper arm and forearm is a = 86°. Length of upper arm: Lupp = 0.4 m Length of forearm: fore = 0.31 m What is the linear velocity of the wrist vw? Answer: Vw = + 1.311 m S PALDING W î+ 1.168 m Ĵ
