Due to a lack of a computer network, you try sending messages through the Reichswald Sherwood forest with the help of kinematics: You fully stretch a bow according to Hooke’s law with a force of 200 N. Measure the full displacement, i.e. the length of your arm x. Compute the force and the acceleration the arrow (m=0.15 kg) experiences half stretched and fully released.
