A man is standing facing the positive “x” direction. He starts a reaching task with approximately 0° of shoulder flexion and 120° of elbow flexion. He accelerates his joints. His height is 163 cm, and the length of both his upper arm and forearm are 16.5% of his height.

I found the angular acceleration, angular velocity, and angular position of his shoulder and elbow joints through an excel sheet.

But how do I find

a. The position of her hand in the horizontal direction?
