L'objectif de ce problème est de préparer l'analyse d'un enregistrement en termes de variation de vecteur vitesse et de relier cette variation à l'existence d'actions.
Le lancer de marteau est une discipline olympique qui consiste à lancer un boulet après l'avoir accéléré en le
faisant tourner au bout d'un câble. Sur le schéma ci-dessous, on montre les positions successives B, à Bie du
boulet, résultat d'une simulation à partir de données réelles : le lanceur utilise un boulet de masse m = 4 kg, un
câble de longueur L = 2,5 m et lâche le boulet lorsqu'il a une vitesse de 25 m. st.
On rappelle que le périmètre P d'un cercle de rayon r vaut p = 2 xnxr.

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.
